Traditional unit tests. These tests usually focus on testing one very specific test case at a time. For example, [MethodTest](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/test/java/com/google/api/generator/gapic/model/MethodTest.java) +2. Golden unit tests. These tests start with a test proto, we create different test cases in the proto, load the proto in unit tests and save the generated file as golden files. For example, [routing header proto](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/test/proto/explicit_dynamic_routing_header_testing.proto) -> Load in the [unit test](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/test/java/com/google/api/generator/gapic/composer/grpc/GrpcServiceStubClassComposerTest.java#L56-L64) -> Saved as [golden](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/test/java/com/google/api/generator/gapic/composer/grpc/goldens/GrpcRoutingHeadersStub.golden) +3. Showcase integration tests. They test the generated library's behavior against a mock server, see [README.md](https://github.com/googleapis/sdk-platform-java/blob/main/java-showcase/README.md) of showcase module for details. +4. Golden integration tests. These tests generate a full client library with real protos from googleapis, for example, golden integration tests for [compute](https://github.com/googleapis/sdk-platform-java/tree/main/test/integration/goldens/compute). However, we _should_ stop adding new ones, and rely on golden unit tests and showcase tests. -To generate a production GAPIC API: - -1.

Overview + +This repository, `sdk-platform-java`, is a monorepo containing the foundational components for building Java client libraries for Google Cloud Platform services. It includes the GAPIC (Generated API Client) generator for Java, the GAX (Google API Extensions) runtime library, and other shared modules. + +## 2. Project Structure + +The repository is structured into several key modules: + +* **`gapic-generator-java`**: The core component for creating new client libraries. It is a Protobuf compiler plugin that generates Java client libraries from API definition files. The `DEVELOPMENT.md` file in this module provides detailed information on how to work with the generator. + +* **`gax-java`**: The Google API Extensions for Java (GAX) library. It provides runtime support for the generated client libraries, including features like pagination, request batching, and polling of long-running operations. It has the following submodules: + * `gax`: Transport-independent part of GAX for Java. + * `gax-grpc`: gRPC-specific logic for GAX. + * `gax-httpjson`: REST-specific logic for GAX. + +* **`api-common-java`**: Contains foundational types and utilities related to Google APIs. It includes the following packages: + * `core`: Core library containing API stability annotations and wrappers around Guava types. + * `pathtemplate`: Path Template library for manipulating strings that are formatted as Google API resource names. + * `resourcenames`: Resource Name library used by generated resource name types. + +* **`java-common-protos`**: Provides Protobuf-generated classes for common Google services that are used across multiple APIs. The code is in this module is auto-generated and should not be modified. + +* **`java-iam`**: Contains Protobuf-generated classes for Google's Identity and Access Management (IAM) service, used for managing policies. The code is in this module is auto-generated and should not be modified. + +* **`java-showcase`**: A demonstration client library for the "Showcase" API, which is a fake API used for integration testing of the GAPIC generator and GAX library. + +* **`java-shared-dependencies`**: Manages shared Maven dependencies for all Google Cloud Java client libraries. This ensures consistency and helps avoid dependency conflicts. + +## 3. Getting Started + +### 3.1. Prerequisites + +To build and work with this project, you will need to install: + +* Java 8+ +* Maven + +### 3.2. Building the Project + +The project uses Maven for its primary build system. To build all modules, run the following command from the root of the repository: + +```sh +mvn install +``` + +### 3.3. Code Formatting + +Code formatting is enforced using the `fmt-maven-plugin`. To check for formatting issues, run: + +```sh +mvn fmt:check +``` + +To format the code, run: + +```sh +mvn fmt:format +``` + +## 4. Testing + +### 4.1. Testing Strategy + +The repository employs a multi-layered testing strategy to ensure the quality and correctness of the generated code: + +* **Unit Tests:** Traditional unit tests for individual classes and methods. See [unit testing best practices](https://engdoc.corp.google.com/eng/doc/devguide/testing/unit/best-practices.md?cl=head&polyglot=java). +* **Golden Unit Tests:** These tests generate code from test protos and compare the output to "golden" files, which are pre-approved versions of the generated code. These test cases exist inside the `gapic-generator-java` module. See [GrpcServiceStubClassComposerTest](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/test/java/com/google/api/generator/gapic/composer/grpc/GrpcServiceStubClassComposerTest.java) for an example of golden unit tests. The steps for golden unit tests include creating a test proto, loading the test proto, generating from the test proto, and comparing the result with a golden file. +* **Showcase Integration Tests:** These tests run the generated Showcase client against a local Showcase server to verify end-to-end functionality. This is the preferred way of testing integration tests. +* **Golden Integration Tests:** These tests generate full client libraries for real Google Cloud APIs and compare them to golden versions. This is an older test strategy and showcase testing is preferred. + +Based on where the code changes are, we should add different tests, in general + +* If the changes are in `gax` or `api-common` only, you _must_ add traditional unit tests, you _may_ add showcase integration tests if you are modifying a public setting. +* If the changes are in `gapic-generator-java` only, showcase integration tests are most likely not needed + * If they are in the `composer` module, you _must_ add golden unit tests, you _may_ add traditional unit tests for better coverage and easier testing. + * If they are in the `parser` module, you _should_ add traditional unit tests with a test proto if possible, you _may_ add golden unit tests to easily see the changes. For example, [routing_rule_parser_testing](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/test/proto/routing_rule_parser_testing.proto) that is only used for testing [RoutingRuleParser](https://github.com/googleapis/sdk-platform-java/blob/main/gapic-generator-java/src/main/java/com/google/api/generator/gapic/protoparser/RoutingRuleParser.java). + * If they are in `other modules(ast, model, writer etc.)`, you _must_ add traditional unit tests, you _may_ add golden unit tests to easily see the changes. +- If the changes are in both `gax` and `gapic-generator-java`, you _must_ add all test layers, including traditional unit tests, golden unit tests and showcase integration tests. + +### 4.2. Running Unit Tests + +Unit tests can be tested via this command: + +```sh +mvn test +``` + +### 4.3. Running Golden Integration Tests + +Golden integration tests are run using Bazel. To run all golden integration tests, use the following command from the root of the repository: + +```sh +bazelisk test //... +``` + +Specific integration tests can be run by specifying the target, for example: + +```sh +bazelisk test //test/integration:redis +``` + +### 4.4. Updating Golden Files + +If you make changes that affect the generated code, you will need to update the golden files. This can be done using the following command: + +```sh +bazelisk run //test/integration:update_asset && bazelisk run //test/integration:update_credentials && bazelisk run //test/integration:update_iam && bazelisk run //test/integration:update_kms && bazelisk run //test/integration:update_pubsub && bazelisk run //test/integration:update_logging && bazelisk run //test/integration:update_redis && bazelisk run //test/integration:update_storage && bazelisk run //test/integration:update_library && bazelisk run //test/integration:update_compute && bazelisk run //test/integration:update_bigtable && bazelisk run //test/integration:update_apigeeconnect +``` + +### 4.5. Running Showcase Integration Tests + +Showcase integration tests are run against a local server that implements the Showcase API. The `java-showcase/README.md` file provides detailed instructions on how to run these tests. The general steps are: + +1. **Install the Showcase server:** + + ```sh + go install github.com/googleapis/gapic-showcase/cmd/gapic-showcase@latest + ``` + +2. **Run the Showcase server:** + + ```sh + gapic-showcase run + ``` + +3. **Run the integration tests:** + + ```sh + cd java-showcase + mvn verify -P enable-integration-tests + ``` + +## 5. Dependency Management + +- Try not to bump any external dependency version unless there is a known CVE (security or vulnerability issue) or a critical bug fix. +- Try to avoid introducing new external dependencies. If a new dependency is required, please state the reason. +- Prefer to use features from the Java standard library, then try to use features from any existing dependencies (preferably from Google managed dependencies). + +## 6. Contribution Guidelines + +- **Commits:** Commit messages should follow the [Conventional Commits](https://www.conventionalcommits.org/) + specification. The format is `: `. The type should be one of the following: fix, feat, + build, chore, docs, test, or refactor. +- **Issues:** All significant changes should start with a GitHub issue. +- **Pull Requests:** All code changes must be submitted via a pull request and require review. Before creating a PR, always pull latest from main, merge main to local branch and resolve any conflicts. +- **Testing:** All new logic should be accompanied by tests. +- For more details, see `CONTRIBUTING.md`. diff --git a/PROPERTIES.bzl b/PROPERTIES.bzl deleted file mode 100644 index 4d5e0f286e..0000000000 --- a/PROPERTIES.bzl +++ /dev/null @@ -1,31 +0,0 @@ -PROPERTIES = { - "version.com_google_protobuf": "3.21.7", - # Version of google-java-format is downgraded from 1.8 to 1.7, because 1.8 supports java 11 minimum, while our JRE is java 8. - "version.google_java_format": "1.7", - "version.io_grpc_java": "1.42.1", - - # Common deps. - "maven.com_google_guava_guava": "com.google.guava:guava:30.1-android", - "maven.com_google_code_findbugs_jsr305": "com.google.code.findbugs:jsr305:3.0.0", - "maven.com_google_auto_value_auto_value": "com.google.auto.value:auto-value:1.7.2", - "maven.com_google_auto_value_auto_value_annotations": "com.google.auto.value:auto-value-annotations:1.7.2", - "maven.com_google_code_gson": "com.google.code.gson:gson:2.8.6", - "maven.com_google_protobuf_protobuf_java": "com.google.protobuf:protobuf-java:3.21.7", - "maven.io_github_java_diff_utils": "io.github.java-diff-utils:java-diff-utils:4.11", - "maven.javax_annotation_javax_annotation_api": "javax.annotation:javax.annotation-api:1.3.2", - - # Gapic YAML parsing for batching settings. - "maven.org_yaml_snakeyaml": "org.yaml:snakeyaml:1.26", - - # ServiceStubSettings class.

        NestedMessageMethod

        		 + *

        Request object method variants only take one parameter, a request object, which must be constructed before the call.

        + *
          + *

        • nestedMessageMethod(Outer.Middle request) + *

        + *

        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

        + *
          + *

        • nestedMessageMethodCallable() + *

        + *
        + * + *

        See the individual methods for example code. + * + *

        Many parameters require resource names to be formatted in a particular way. To assist with + * these names, this class includes a format method for each type of name, and additionally a parse + * method to extract the individual identifiers contained within names that are returned. + * + *

        This class can be customized by passing in a custom instance of NestedMessageServiceSettings + * to create(). For example: + * + *

        To customize credentials: + * + * 

        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.

        The default instance has everything set to sensible defaults: + * + *

          + *
        • The default service address (localhost) and default port (7469) are used. + *
        • Credentials are acquired automatically through Application Default Credentials. + *
        • Retries are configured for idempotent methods but not for non-idempotent methods. + *
        + * + *

        The builder of this class is recursive, so contained classes are themselves builders. When + * build() is called, the tree of builders is called to create the complete settings object. + * + *

        For example, to set the + * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings) + * of echoWithVersionMethod: + * + *

+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.

        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of EchoEmpySettings to create().
- * For example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoEmpySettings echoEmpySettings =
- *     EchoEmpySettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * EchoEmpyClient echoEmpyClient = EchoEmpyClient.create(echoEmpySettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoEmpySettings echoEmpySettings =
- *     EchoEmpySettings.newBuilder().setEndpoint(myEndpoint).build();
- * EchoEmpyClient echoEmpyClient = EchoEmpyClient.create(echoEmpySettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoEmpySettings echoEmpySettings = EchoEmpySettings.newHttpJsonBuilder().build();
- * EchoEmpyClient echoEmpyClient = EchoEmpyClient.create(echoEmpySettings);
- * }
        
- *
- *

        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *

+ *       
        
+ *
+ * 
        See the individual methods for example code.
+ *
+ * 
        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of WickedSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * WickedSettings wickedSettings =
+ *     WickedSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * WickedClient wickedClient = WickedClient.create(wickedSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * WickedSettings wickedSettings = WickedSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * WickedClient wickedClient = WickedClient.create(wickedSettings);
+ * }
        
+ *

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link WickedClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of craftEvilPlan:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * WickedSettings.Builder wickedSettingsBuilder = WickedSettings.newBuilder();
+ * wickedSettingsBuilder
+ *     .craftEvilPlanSettings()
+ *     .setRetrySettings(
+ *         wickedSettingsBuilder
+ *             .craftEvilPlanSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * WickedSettings wickedSettings = wickedSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link WickedStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of craftEvilPlan:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * WickedStubSettings.Builder wickedSettingsBuilder = WickedStubSettings.newBuilder();
+ * wickedSettingsBuilder
+ *     .craftEvilPlanSettings()
+ *     .setRetrySettings(
+ *         wickedSettingsBuilder
+ *             .craftEvilPlanSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());

+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link EchoStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the total timeout of echo to 30 seconds:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * EchoStubSettings echoSettings = echoSettingsBuilder.build();
+ * }

-One-time setup
-==============
-
-Set up Sonatype Account
------------------------
-* Sign up for a Sonatype JIRA account [here](https://issues.sonatype.org)
-* Click *Sign Up* in the login box, follow instructions
-
-Get access to repository
-------------------------
-* Go to [community support](https://issues.sonatype.org/browse/OSSRH)
-* Ask for publish rights by creating an issue similar to [this one](https://issues.sonatype.org/browse/OSSRH-32031)
-  * You must be logged in to create a new issue
-  * Use the *Create* button at the top tab
-
-* Generate the key `gpg --gen-key`
-  * Keep the defaults, but specify a passphrase
-
-* Determine your `gpg` version: `gpg --version`
-
-* Find the ID of your public key
-  * If you're using GPG version 1.y.z, `gpg --list-secret-keys`
-    * Look for the line with format `sec   2048R/ABCDEFGH 2015-11-17`
-    * The `ABCDEFGH` is the ID for your public key
-  * If you're using GPG version 2.y.z `gpg --list-secret-keys --keyid-format LONG`
-    * Look for line with format `sec   rsa2048/ABCDEFGHIJKLMNOP`
-    * The `ABCDEFGHIJKLMNOP` is the ID. It is 16-byte long, but Gradle
-      only support 8-byte keys. Use the *last* 8 bytes of the key when
-      following the rest of this document.
-    * `gpg --export-secret-keys > $HOME/.gnupg/secring.gpg`
-
-* Upload your public key to a public server: `gpg --send-keys --keyserver hkp://pgp.mit.edu `
-
-Add deploy credential settings
-------------------------
-* Create a settings file at `$HOME/.gradle/gradle.properties` with your key information and your sonatype username/password
-
-```
-signing.keyId=
-signing.password=
-signing.secretKeyRingFile=/usr/local/google/home//.gnupg/secring.gpg
-
-ossrhUsername=
-ossrhPassword=
-```
-
-Install releasetool
--------------------
-See [releasetool](https://github.com/googleapis/releasetool) for installation instructions. You will
-need python 3.6+ to run this tool.
-
-To prepare a release
-====================
-
-Update version and deploy to Sonatype
--------------------------------------
-1. Run `releasetool start`. Select "minor" or "patch" for the release type. This will bump the
-   artifact versions, ask you to edit release notes, and create the release pull request. When
-   prompted, choose to autorelease.
-  * Note: be sure to make these notes nice as they will be used for the release notes as well.
-2. Request a review on the PR.
-3. Submit the PR.
-4. Automation will run in the background to handle the release.
-5. It will take some time (~10 min to ~8 hours) for the package to transition
-6. Automation will publish a new release on Github using releasetool and publish javadocs to
-   https://googleapis.dev/java/gax/latest.
-
-Bump development version
-------------------------
-1. Run `releasetool start` again, but specify "snapshot" when prompted for the type of release.
-   This will bump the artifact versions and create a new snapshot pull request.
-2. Review and submit the PR.

-#
-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.
-#

+
+The integration tests build the docker image declared in

+definitions and GAPIC repositories, generate the libraries and compare the
+results with the source code declared in a "golden branch" of the repo.
+
+The integration tests are running in Cloud Build rather than GitHub workflow
+because the workflow doesn't have permission to pull images from Airlock.
+
+The Cloud Build job is defined in `.cloudbuild/library_generation/cloudbuild-library-generation-integration-test.yaml` and runs in every pull request.
+
+# Run the unit tests
+
+There is one unit test file per component.
+Every unit test script ends with `unit_tests.py`.
+To avoid specifying them individually, we can use the following command:

+```shell
+python -m unittest discover -s hermetic_build -p "*unit_tests.py"
+```
+
+> [!NOTE]
+> The output of this command may look erratic during the first 30 seconds.
+> This is normal. After the tests are done, an "OK" message should be shown.
+
+# Run the library generation scripts in your local environment
+
+Although the scripts are designed to run in a Docker container, you can also
+run them directly.
+This section explains how to run the entrypoint script
+(`hermetic_build/library_generation/cli/entry_point.py`).
+
+## Assumptions made by the scripts
+
+### The Hermetic Build's well-known folder
+Located in `${HOME}/.library_generation`, this folder is assumed by the scripts
+to contain certain tools.
+
+Developers must make sure this folder is properly configured before running the
+scripts locally.
+Note that this relies on the `HOME` environment variable which is always defined
+as per [POSIX env var definition](https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html).
+
+#### Put the gapic-generator-java jar in its well-known location
+
+1. Run the following command to install gapic-generator-java.
+
+   ```shell
+   mvn install -B -ntp -DskipTests -Dclirr.skip -Dcheckstyle.skip
+   ```
+   This will generate a jar located in `~/.m2/repository/com/google/api/gapic-generator-java/{version}/gapic-generator-java-{version}.jar`
+
+2. Move the jar into its well-known location.
+
+   ```shell
+   mv /path/to/jar "${HOME}/.library_generation/gapic-generator-java.jar"
+   ```
+
+#### Put the protobuf compiler in its well-known location
+1. Download protobuf compiler from [GitHub releases](https://github.com/protocolbuffers/protobuf/releases).
+2. Move the folder into its well-know location.
+
+   ```shell
+   unzip /path/to/zipfile -d "${HOME}/.library_generation/"
+   ```
+#### Put the GRPC plugin in its well-known location
+1. Download GRPC plugin from [Maven Central](https://central.sonatype.com/artifact/io.grpc/protoc-gen-grpc-java/versions).
+2. Move the folder into its well-know location.
+
+   ```shell
+   mv /path/to/protoc-gen-grpc-java.exe "${HOME}/.library_generation/protoc-gen-grpc-java.exe"
+   ```
+
+#### Put the java formatter jar in its well-known location
+
+1. Download google-java-format-{version}-all-deps.jar from [Maven Central](https://central.sonatype.com/artifact/com.google.googlejavaformat/google-java-format)
+or [GitHub releases](https://github.com/google/google-java-format/releases).
+2. Move the jar into its well-known location.
+
+   ```shell
+   mv /path/to/jar "${HOME}/.library_generation/google-java-format.jar"
+   ```
+
+## Installing prerequisites
+
+In order to run the generation scripts directly, there are a few tools we
+need to install beforehand.
+
+### Install the owl-bot CLI
+
+This requires node.js to be installed.
+Check this [installation guide](https://github.com/nvm-sh/nvm?tab=readme-ov-file#install--update-script)
+for NVM, Node.js's version manager.
+
+After you install it, you can install the owl-bot CLI with the following
+commands:
+
+```shell
+git clone https://github.com/googleapis/repo-automation-bots
+cd repo-automation-bots/packages/owl-bot
+npm i && npm run compile && npm link
+owl-bot copy-code --version
+```
+
+The key step is `npm link`, which will make the command available in you current
+shell session.
+
+If you get a permission denied error when running the command `owl-bot`, try
+relinking owl-bot by running `npm unlink -g` and re-running the steps above.
+
+## Run the script
+The entrypoint script (`hermetic_build/library_generation/cli/entry_point.py`)
+allows you to generate a GAPIC repository with a given api definition (proto,
+service yaml).
+
+### Download the api definition
+For example, from googleapis
+
+```shell
+git clone https://github.com/googleapis/googleapis
+export api_definitions_path="$(pwd)/googleapis"
+```
+
+### Download the repo
+For example, google-cloud-java
+```shell
+git clone https://github.com/googleapis/google-cloud-java
+export path_to_repo="$(pwd)/google-cloud-java"
+```
+
+### Install the scripts
+
+You can skip this step if you've installed the packages in [Install package dependencies](#install-package-dependencies).
+Use the `--editable` flag for your changes to take effect as soon as you modify any file inside
+the package.
+
+```shell
+python -m pip install --require-hashes -r hermetic_build/common/requirements.txt
+python -m pip install --editable hermetic_build/common
+python -m pip install --require-hashes -r hermetic_build/library_generation/requirements.txt
+python -m pip install --editable hermetic_build/library_generation
+```
+
+### Run the script
+
+```shell
+python hermetic_build/library_generation/cli/entry_point.py generate \
+   --repository-path="${path_to_repo}" \
+   --api-definitions-path="${api_definitions_path}"
+```
+
+# Build the image from source
+
+1. Run the following command to build the image from source
+
+   ```shell
+   DOCKER_BUILDKIT=1 docker build \
+     -f .cloudbuild/library_generation/library_generation.Dockerfile \
+     -t local:image-tag \
+     .
+   ```
+   Please note that the build only works when using the new [Docker BuildKit](https://docs.docker.com/build/buildkit/)
+   (enabled through the `DOCKER_BUILDKIT` variable).
+   
+2. Set the version of gapic-generator-java
+
+   ```shell
+   LOCAL_GENERATOR_VERSION=$(mvn \
+     org.apache.maven.plugins:maven-help-plugin:evaluate \
+     -Dexpression=project.version \
+     -pl gapic-generator-java \
+     -DforceStdout \
+     -q)
+   ```
+
+3. Run the image
+
+   ```shell
+      # Assume you want to generate the library in the current working directory
+      # and the generation configuration is in the same directory.
+      docker run \
+        --rm \
+        --quiet \
+        -u "$(id -u):$(id -g)" \
+        -v "$(pwd):/workspace" \
+        -v /path/to/api-definitions:/workspace/apis \
+        -e GENERATOR_VERSION="${LOCAL_GENERATOR_VERSION}" \
+        local:image-tag \
+        --generation-config-path=/workspace/generation_config_file \
+        --library-names=apigee-connect,asset \
+        --repository-path=/workspace \
+        --api-definitions-path=/workspace/apis
+   ```
+
+# Debugging tips
+## Debug the scripts
+Especially on local setups, consider adding the `xtrace` (`set -x`) flag to
+ - `hermetic_build/library_generation/generate_library.sh`
+ - `hermetic_build/library_generation/utils/utilities.sh`
+
+This will allow you to observe how the tools you prepared in `~/.library_generation` are being used.
+
+
+## Debug the library generation container
+If you are working on changing the way the containers are created, you may want
+to inspect the containers to check the setup.
+It would be convenient in such case to have a text editor/viewer available.
+You can achieve this by modifying the Dockerfile as follows:
+
+```dockerfile
+# install OS tools
+RUN apk update && apk add \
+	unzip curl rsync openjdk11 jq bash nodejs npm git less vim
+```
+
+We add `less` and `vim` as text tools for further inspection.
+
+You can also run a shell in a new container by running:
+
+```shell
+docker run \
+  --rm \
+  -it \
+  -u $(id -u):$(id -g) \
+  -v /path/to/google-cloud-java:/workspace \
+  --entrypoint="bash" \
+  $(cat image-id)
+```

+# Generate a repository containing GAPIC Client Libraries
+
+Running the docker image built from `hermetic_build/library_generation`
+directory, you can generate a repository containing GAPIC client libraries (a
+monorepo, for example, google-cloud-java) from a configuration file.
+
+## Environment
+
+- OS: Linux
+- Docker
+
+## Prerequisites
+
+### Generation configuration
+
+A generation configuration file is required to generate GAPIC Client Libraries.
+
+Please refer to [Generation configuration](#configuration-to-generate-a-repository)
+for more information.
+
+### versions.txt
+
+In order to generate a version for each library, a `versions.txt` has to exist
+in `repository-path`.
+Please refer to [Repository path](#repository-path-repository-path-optional)
+for more information.
+
+## Parameters to generate a repository using the docker image
+
+### Generation configuration yaml (`generation-config-path`), optional
+
+An absolute or relative path to a configuration file containing parameters to
+generate the repository.
+Please refer to [Configuration to generate a repository](#configuration-to-generate-a-repository)
+for more information.
+
+The default value is `$(pwd)/generation_config.yaml`, i.e., `generation_config.yaml`
+in the current working directory.
+
+This will raise `FileNotFoundError` if the specified generation config does not
+exist or, in case `generation-config-path` is not specified, the default
+generation config does not exist.
+
+### Repository path (`repository-path`), optional
+
+The path to where the generated repository goes.
+
+The default value is the current working directory when running the script.
+For example, `cd google-cloud-java && python /path/to/entry_point.py ...` without
+specifying the `--repository_path` option will modify the `google-cloud-java`
+repository the user `cd`'d into.
+
+Note that `versions.txt` has to exist in `repository_path` in order to generate
+the right version for each library.
+Please refer go/java-client-releasing#versionstxt-manifest for more info
+of versions.txt.
+
+### A list of library names (`library-names`), optional
+
+A list of library names that will be generated, separated by comma.
+The library name of a library is the value of `library_name` or `api_shortname`,
+if `library_name` is not specified, in the generation configuration.
+
+If not specified, all libraries in the generation
+configuration will be generated.
+
+### Api definitions path (`api-definitions-path`), optional
+
+The path to where the api definition (proto, service yaml) resides.
+
+The default value is the current working directory when running the script.
+
+**Note that you need not only the protos defined the service, but also the
+transitive dependencies of those protos.**
+Any missing dependencies will cause `File not found` error.
+
+For example, if your service is defined in `example_service.proto` and it
+imports `google/api/annotations.proto`, you need the `annotations.proto` resides
+in a folder that has the exact structure of the import statement (`google/api`
+in this case), and set `api_definitions_path` to the path contains the root
+folder (`google` in this case).
+
+## Output
+
+### GAPIC libraries
+
+For each module (e.g. `google-cloud-java/java-asset`), the following
+files/folders will be created/modified:

+## Configuration to generate a repository
+
+There are three levels of parameters in the configuration: repository level,
+library level and GAPIC level.
+
+### Repository level parameters
+
+The repository level parameters define the version of API definition (proto)
+and tools.
+They are shared by library level parameters.
+

+
+### Library level parameters
+
+The library level parameters define how to generate a (multi-versions) GAPIC
+library.
+They are shared by all GAPICs of a library.
+
+| Name                  | Required | Notes                                                                                                                                     |

+
+# Run the library generation image
+
+1. Download the API definitions to a local directory, e.g., from [googleapis](https://github.com/googleapis/googleapis).
+
+2. Run the docker image.
+   ```shell
+   # Assume you want to generate the library in the current working directory
+   # and the generation configuration is in the same directory.
+   docker run \
+     --rm \
+     --quiet \
+     -u "$(id -u):$(id -g)" \
+     -v "$(pwd):/workspace" \
+     -v /path/to/api_definition:/workspace/apis \
+     gcr.io/cloud-devrel-public-resources/java-library-generation:image-tag
+   ```
+
+   * `-u "$(id -u)":"$(id -g)"` makes docker run the container impersonating
+     yourself. 
+     This avoids folder ownership changes since it runs as root by default.
+   * `-v "$(pwd):/workspace"` maps the host machine's current working directory
+     to the /workspace folder. 
+     The image is configured to perform changes in this directory.
+   * `-v /path/to/api_definition:/workspace/apis` maps the host machine's API 
+     definitions folder to `/workspace/apis` folder.
+ 
+3. An advanced example:
+   ```shell
+   docker run \
+     --rm \
+     --quiet \
+     -u "$(id -u):$(id -g)" \
+     -v "$(pwd):/workspace" \
+     -v /path/to/api_definition:/workspace/apis \
+     gcr.io/cloud-devrel-public-resources/java-library-generation:image-tag \
+     --generation-config-path=/workspace/generation_config_file \
+     --library-names=apigee-connect,asset \
+     --repository-path=/workspace \
+     --api-definitions-path=/workspace/apis
+   ```
+    
+   * `--generation-config-path=/workspace/generation_config_file` set the
+     generation configuration to `/workspace/generation_config_file`.
+   * `--api-definitions-path=/workspace/apis` set the API definition path to
+     `/workspace/apis`.
+
+To debug the image, please refer to [development guide](DEVELOPMENT.md#debug-the-library-generation-container)
+for more info.

+# Generate release notes from API definition changes
+
+The script, `hermetic_build/release_note_generation/cli/generate_release_note.py`
+allows you to generate a file containing release notes from API definition
+changes in [googleapis](https://github.com/googleapis/googleapis) GitHub
+repository.
+
+## Environment
+
+- OS: Linux
+- Python (3.12.0 or above)
+
+## Parameters to generate a release note
+
+### Baseline generation configuration path (`baseline-generation-config-path`)
+
+Absolute or relative path to a generation configuration.
+Please refer to [Configuration to generate a repository](#configuration-to-generate-a-repository)
+for more information.
+
+Note that the `googleapis_commitish` in this configuration is used to retrieve
+the first commit, exclusively, to generate the release notes.
+
+### Current generation configuration path (`current-generation-config-path`)
+
+Absolute or relative path to a generation configuration.
+The release notes will be generated from commits that are related to the
+libraries specified in this configuration.
+Please refer to [Configuration to generate a repository](#configuration-to-generate-a-repository)
+for more information.
+
+Note that the `googleapis_commitish` entry in this configuration is used to
+retrieve the last commit, inclusively, to generate the release notes.
+
+### Repository path (`repository-path`), optional
+
+The path to which the file, `pr_description.txt` containing the release notes
+will be sent.
+If not specified, the file will be generated to the current working directory.
+
+## Generate a release notes file in a local environment
+
+1. Install python (>= 3.12.0).
+It is recommended to create a python virtual environment through the
+[official guide](https://packaging.python.org/en/latest/guides/installing-using-pip-and-virtual-environments/#create-and-use-virtual-environments).
+
+2. Run the following commands to install python packages
+   ```shell
+   cd /path/to/sdk-platform-java 
+   pip install --require-hashes -r hermetic_build/common/requirements.txt
+   pip install hermetic_build/common
+   pip install --require-hashes -r hermetic_build/release_note_generation/requirements.txt
+   pip install hermetic_build/release_note_generation
+   ```
+3. Run the following commands to generate a release note
+   ```shell
+   cd /path/to/sdk-platform-java 
+   python hermetic_build/release_note_generation/cli/generate_release_note.py generate \
+     --baseline-generation-config-path=/path/to/baseline_generation_config \
+     --current-generation-config-path=/path/to/current_generation_config \
+     --repository-path=/path/to/send/release_note
+   ```
+
+# OwlBot Java Postprocessor
+
+We have transferred the
+[implementation](https://github.com/googleapis/synthtool/tree/59fe44fde9866a26e7ee4e4450fd79f67f8cf599/docker/owlbot/java)
+of Java Owlbot Postprocessor into `sdk-platform-java/hermetic_build/library_generation`.
+
+## Reflecting changes in synthtool/docker/owlbot/java into this repository
+The transfer was not a verbatim copy, it rather had modifications:
+ * `format-source.sh` was replaced by a call to `mvn fmt:format`
+ * `entrypoint.sh` was modified to have input arguments and slightly modified
+   the way the helper scripts are called
+ * Other helper scripts were modified to have input arguments.
+ * `fix_poms.py` modified the way the monorepo is detected
+
+All these modifications imply that whenever we want to reflect a change from the
+original owlbot in synthtool we may be better off modifying the affected source
+files one by one. The mapping is from
+[`synthtool/docker/owlbot/java`](https://github.com/googleapis/synthtool/tree/59fe44fde9866a26e7ee4e4450fd79f67f8cf599/docker/owlbot/java)
+to
+[`sdk-platform-java/library_generation/owlbot`](https://github.com/googleapis/sdk-platform-java/tree/move-java-owlbot/library_generation/owlbot)

+"""
+This script allows generation of libraries that are composed of more than one
+service version. It is achieved by calling `generate_library.sh` without
+postprocessing for all service versions and then calling
+postprocess_library.sh at the end, once all libraries are ready.
+
+Prerequisites
+- Needs a folder named `output` in current working directory. This folder
+is automatically detected by `generate_library.sh` and this script ensures it
+contains the necessary folders and files, specifically:
+  - A "google" folder found in the googleapis/googleapis repository
+  - A "grafeas" folder found in the googleapis/googleapis repository
+Note: googleapis repo is found in https://github.com/googleapis/googleapis.

+# How to Contribute
+
+We'd love to accept your patches and contributions to this project. There are
+just a few small guidelines you need to follow.
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution;
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to  to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Code reviews
+
+All submissions, including submissions by project members, require review. We
+use GitHub pull requests for this purpose. Consult
+[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
+information on using pull requests.
+
+## Community Guidelines
+
+This project follows
+[Google's Open Source Community Guidelines](https://opensource.google.com/conduct/).
+
+## Building the project
+
+To build, package, and run all unit tests run the command
+
+```
+mvn clean verify
+```
+
+### Running Integration tests
+
+To include integration tests when building the project, you need access to
+a GCP Project with a valid service account. 
+
+For instructions on how to generate a service account and corresponding
+credentials JSON see: [Creating a Service Account][1].
+
+Then run the following to build, package, run all unit tests and run all
+integration tests.
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
+mvn -Penable-integration-tests clean verify
+```
+
+## Code Samples
+
+All code samples must be in compliance with the [java sample formatting guide][3].
+Code Samples must be bundled in separate Maven modules.
+
+The samples must be separate from the primary project for a few reasons:
+1. Primary projects have a minimum Java version of Java 8 whereas samples can have
+   Java version of Java 11. Due to this we need the ability to
+   selectively exclude samples from a build run.
+2. Many code samples depend on external GCP services and need
+   credentials to access the service.
+3. Code samples are not released as Maven artifacts and must be excluded from 
+   release builds.
+   
+### Building
+
+```bash
+mvn clean verify
+```
+
+Some samples require access to GCP services and require a service account:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
+mvn clean verify
+```
+
+### Code Formatting
+
+Code in this repo is formatted with
+[google-java-format](https://github.com/google/google-java-format).
+To run formatting on your project, you can run:
+```
+mvn com.spotify.fmt:fmt-maven-plugin:format
+```

+## Authentication
+
+See the [Authentication][authentication] section in the base directory's README.
+
+## Authorization
+
+The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired {{metadata['repo']['name_pretty']}} APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the {{metadata['repo']['name_pretty']}} API calls.
+
+## Getting Started
+
+### Prerequisites
+
+You will need a [Google Cloud Platform Console][developer-console] project with the {{metadata['repo']['name_pretty']}} [API enabled][enable-api].
+{% if metadata['repo']['requires_billing'] %}You will need to [enable billing][enable-billing] to use Google {{metadata['repo']['name_pretty']}}.{% endif %}
+[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
+[installing the Google Cloud Command Line Interface][cloud-cli] and running the following commands in command line:
+`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
+
+### Installation and setup
+
+You'll need to obtain the `{{ artifact_id }}` library.  See the [Quickstart](#quickstart) section
+to add `{{ artifact_id }}` as a dependency in your code.
+
+## About {{metadata['repo']['name_pretty']}}
+
+{% if 'partials' in metadata and metadata['partials']['about'] -%}
+{{ metadata['partials']['about'] }}
+{% else %}
+[{{ metadata['repo']['name_pretty'] }}][product-docs] {{ metadata['repo']['api_description'] }}

+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
+
+{% if metadata['repo']['transport'] -%}
+## Transport
+
+{% if metadata['repo']['transport'] == 'grpc' -%}
+{{metadata['repo']['name_pretty']}} uses gRPC for the transport layer.
+{% elif metadata['repo']['transport'] == 'http' -%}
+{{metadata['repo']['name_pretty']}} uses HTTP/JSON for the transport layer.
+{% elif metadata['repo']['transport'] == 'both' -%}
+{{metadata['repo']['name_pretty']}} uses both gRPC and HTTP/JSON for the transport layer.
+{% endif %}
+{% endif -%}
+
+## Supported Java Versions
+
+Java {{ metadata['min_java_version'] }} or above is required for using this client.
+
+Google's Java client libraries,
+[Google Cloud Client Libraries][cloudlibs]
+and
+[Google Cloud API Libraries][apilibs],
+follow the
+[Oracle Java SE support roadmap][oracle]
+(see the Oracle Java SE Product Releases section).
+
+### For new development
+
+In general, new feature development occurs with support for the lowest Java
+LTS version covered by  Oracle's Premier Support (which typically lasts 5 years
+from initial General Availability). If the minimum required JVM for a given
+library is changed, it is accompanied by a [semver][semver] major release.
+
+Java 11 and (in September 2021) Java 17 are the best choices for new
+development.
+
+### Keeping production systems current
+
+Google tests its client libraries with all current LTS versions covered by
+Oracle's Extended Support (which typically lasts 8 years from initial
+General Availability).
+
+#### Legacy support
+
+Google's client libraries support legacy versions of Java runtimes with long
+term stable libraries that don't receive feature updates on a best efforts basis
+as it may not be possible to backport all patches.
+
+Google provides updates on a best efforts basis to apps that continue to use
+Java 7, though apps might need to upgrade to current versions of the library
+that supports their JVM.
+
+#### Where to find specific information
+
+The latest versions and the supported Java versions are identified on
+the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
+and on [google-cloud-java][g-c-j].
+
+## Versioning
+
+{% if 'partials' in metadata and metadata['partials']['versioning'] -%}
+{{ metadata['partials']['versioning'] }}
+{% else %}
+This library follows [Semantic Versioning](http://semver.org/).
+
+{% if metadata['repo']['release_level'] in ['preview'] %}
+It is currently in major version zero (``0.y.z``), which means that anything may change at any time
+and the public API should not be considered stable.
+{% endif %}{% endif %}

+# 3 - versions_file: path to file containing versions to be applied to the poms
+# 4 - owlbot_cli_source_folder: alternative folder with a structure exactly like
+# googleapis-gen. It will be used instead of preprocessed_sources_path if
+# 5 - is_monorepo: whether this library is a monorepo, which implies slightly
+# different logic

+# Google Cloud Asset Inventory Client for Java
+
+Java idiomatic client for [Cloud Asset Inventory][product-docs].
+
+[![Maven][maven-version-image]][maven-version-link]
+![Stability][stability-image]
+
+- [Product Documentation][product-docs]
+- [Client Library Documentation][javadocs]
+
+
+:bus: In October 2022, this library has moved to
+[google-cloud-java/java-asset](
+https://github.com/googleapis/google-cloud-java/tree/main/java-asset).
+This repository will be archived in the future.
+Future releases will appear in the new repository (https://github.com/googleapis/google-cloud-java/releases).
+The Maven artifact coordinates (`com.google.cloud:google-cloud-asset`) remain the same.
+
+## Quickstart
+
+
+If you are using Maven, add this to your pom.xml file:
+
+
+```xml
+
+  com.google.cloud
+  google-cloud-asset
+  1.2.3
+
+```
+
+If you are using Gradle without BOM, add this to your dependencies:
+
+```Groovy
+implementation 'com.google.cloud:google-cloud-asset:1.2.3'
+```
+
+If you are using SBT, add this to your dependencies:
+
+```Scala
+libraryDependencies += "com.google.cloud" % "google-cloud-asset" % "1.2.3"
+```
+
+## Authentication
+
+See the [Authentication][authentication] section in the base directory's README.
+
+## Authorization
+
+The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired Cloud Asset Inventory APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the Cloud Asset Inventory API calls.
+
+## Getting Started
+
+### Prerequisites
+
+You will need a [Google Cloud Platform Console][developer-console] project with the Cloud Asset Inventory [API enabled][enable-api].
+You will need to [enable billing][enable-billing] to use Google Cloud Asset Inventory.
+[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
+[installing the Google Cloud Command Line Interface][cloud-cli] and running the following commands in command line:
+`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
+
+### Installation and setup
+
+You'll need to obtain the `google-cloud-asset` library.  See the [Quickstart](#quickstart) section
+to add `google-cloud-asset` as a dependency in your code.
+
+## About Cloud Asset Inventory
+
+
+[Cloud Asset Inventory][product-docs] provides inventory services based on a time series database. This database keeps a five week history of Google Cloud asset metadata. The Cloud Asset Inventory export service allows you to export all asset metadata at a certain timestamp or export event change history during a timeframe.
+
+See the [Cloud Asset Inventory client library docs][javadocs] to learn how to
+use this Cloud Asset Inventory Client Library.
+
+
+
+
+
+
+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
+
+## Transport
+
+Cloud Asset Inventory uses gRPC for the transport layer.
+
+## Supported Java Versions
+
+Java 8 or above is required for using this client.
+
+Google's Java client libraries,
+[Google Cloud Client Libraries][cloudlibs]
+and
+[Google Cloud API Libraries][apilibs],
+follow the
+[Oracle Java SE support roadmap][oracle]
+(see the Oracle Java SE Product Releases section).
+
+### For new development
+
+In general, new feature development occurs with support for the lowest Java
+LTS version covered by  Oracle's Premier Support (which typically lasts 5 years
+from initial General Availability). If the minimum required JVM for a given
+library is changed, it is accompanied by a [semver][semver] major release.
+
+Java 11 and (in September 2021) Java 17 are the best choices for new
+development.
+
+### Keeping production systems current
+
+Google tests its client libraries with all current LTS versions covered by
+Oracle's Extended Support (which typically lasts 8 years from initial
+General Availability).
+
+#### Legacy support
+
+Google's client libraries support legacy versions of Java runtimes with long
+term stable libraries that don't receive feature updates on a best efforts basis
+as it may not be possible to backport all patches.
+
+Google provides updates on a best efforts basis to apps that continue to use
+Java 7, though apps might need to upgrade to current versions of the library
+that supports their JVM.
+
+#### Where to find specific information
+
+The latest versions and the supported Java versions are identified on
+the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
+and on [google-cloud-java][g-c-j].

-# Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of
-experience, education, socio-economic status, nationality, personal appearance,
-race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-*   Using welcoming and inclusive language
-*   Being respectful of differing viewpoints and experiences
-*   Gracefully accepting constructive criticism
-*   Focusing on what is best for the community
-*   Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-*   The use of sexualized language or imagery and unwelcome sexual attention or
-    advances
-*   Trolling, insulting/derogatory comments, and personal or political attacks
-*   Public or private harassment
-*   Publishing others' private information, such as a physical or electronic
-    address, without explicit permission
-*   Other conduct which could reasonably be considered inappropriate in a
-    professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, or to ban temporarily or permanently any
-contributor for other behaviors that they deem inappropriate, threatening,
-offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-This Code of Conduct also applies outside the project spaces when the Project
-Steward has a reasonable belief that an individual's behavior may have a
-negative impact on the project or its community.
-
-## Conflict Resolution
-
-We do not believe that all conflict is bad; healthy debate and disagreement
-often yield positive results. However, it is never okay to be disrespectful or
-to engage in behavior that violates the project’s code of conduct.
-
-If you see someone violating the code of conduct, you are encouraged to address
-the behavior directly with those involved. Many issues can be resolved quickly
-and easily, and this gives people more control over the outcome of their
-dispute. If you are unable to resolve the matter for any reason, or if the
-behavior is threatening or harassing, report it. We are dedicated to providing
-an environment where participants feel welcome and safe.
-
-Reports should be directed to *googleapis-stewards@google.com*, the
-Project Steward(s) for *Google Cloud Client Libraries*. It is the Project Steward’s duty to
-receive and address reported violations of the code of conduct. They will then
-work with a committee consisting of representatives from the Open Source
-Programs Office and the Google Open Source Strategy team. If for any reason you
-are uncomfortable reaching out to the Project Steward, please email
-opensource@google.com.
-
-We will investigate every complaint, but you may not receive a direct response.
-We will use our discretion in determining when and how to follow up on reported
-incidents, which may range from not taking action to permanent expulsion from
-the project and project-sponsored spaces. We will notify the accused of the
-report and provide them an opportunity to discuss it before any action is taken.
-The identity of the reporter will be omitted from the details of the report
-supplied to the accused. In potentially harmful situations, such as ongoing
-harassment or threats to anyone's safety, we may take action without notice.
-
-## Attribution
-
-This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
-available at
-https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-# How to Contribute
-
-We'd love to accept your patches and contributions to this project. There are
-just a few small guidelines you need to follow.
-
-## Contributor License Agreement
-
-Contributions to this project must be accompanied by a Contributor License
-Agreement. You (or your employer) retain the copyright to your contribution;
-this simply gives us permission to use and redistribute your contributions as
-part of the project. Head over to  to see
-your current agreements on file or to sign a new one.
-
-You generally only need to submit a CLA once, so if you've already submitted one
-(even if it was for a different project), you probably don't need to do it
-again.
-
-## Code reviews
-
-All submissions, including submissions by project members, require review. We
-use GitHub pull requests for this purpose. Consult
-[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
-information on using pull requests.
-
-## Community Guidelines
-
-This project follows
-[Google's Open Source Community Guidelines](https://opensource.google.com/conduct/).
-
-## Building the project
-
-To build, package, and run all unit tests run the command
-
-```
-mvn clean verify
-```
-
-### Running Integration tests
-
-To include integration tests when building the project, you need access to
-a GCP Project with a valid service account. 
-
-For instructions on how to generate a service account and corresponding
-credentials JSON see: [Creating a Service Account][1].
-
-Then run the following to build, package, run all unit tests and run all
-integration tests.
-
-```bash
-export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
-mvn -Penable-integration-tests clean verify
-```
-
-## Code Samples
-
-All code samples must be in compliance with the [java sample formatting guide][3].
-Code Samples must be bundled in separate Maven modules.
-
-The samples must be separate from the primary project for a few reasons:
-1. Primary projects have a minimum Java version of Java 8 whereas samples can have
-   Java version of Java 11. Due to this we need the ability to
-   selectively exclude samples from a build run.
-2. Many code samples depend on external GCP services and need
-   credentials to access the service.
-3. Code samples are not released as Maven artifacts and must be excluded from 
-   release builds.
-   
-### Building
-
-```bash
-mvn clean verify
-```
-
-Some samples require access to GCP services and require a service account:
-
-```bash
-export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
-mvn clean verify
-```
-
-### Code Formatting
-
-Code in this repo is formatted with
-[google-java-format](https://github.com/google/google-java-format).
-To run formatting on your project, you can run:
-```
-mvn com.coveo:fmt-maven-plugin:format
-```

-# Google Common Protos
+# Google Common Protos Client for Java
 
-Java protobuf classes for Google's common protos.
+Java idiomatic client for [Common Protos][product-docs].
 
 [![Maven][maven-version-image]][maven-version-link]
 ![Stability][stability-image]
 
+- [Product Documentation][product-docs]
 - [Client Library Documentation][javadocs]
 
-## Java Versions
 
-Java 7 or above is required for using this client.
+## Quickstart
+
+
+If you are using Maven, add this to your pom.xml file:
+
+
+```xml
+
+  com.google.api.grpc
+  proto-google-common-protos
+  2.39.0
+
+```
+
+If you are using Gradle without BOM, add this to your dependencies:
+
+```Groovy
+implementation 'com.google.api.grpc:proto-google-common-protos:2.39.0'
+```
+
+If you are using SBT, add this to your dependencies:
+
+```Scala
+libraryDependencies += "com.google.api.grpc" % "proto-google-common-protos" % "2.39.0"
+```
+
+## Authentication
+
+See the [Authentication][authentication] section in the base directory's README.
+
+## Authorization
+
+The client application making API calls must be granted [authorization scopes][auth-scopes] required for the desired Common Protos APIs, and the authenticated principal must have the [IAM role(s)][predefined-iam-roles] required to access GCP resources using the Common Protos API calls.
+
+## Getting Started
+
+### Prerequisites
+
+You will need a [Google Cloud Platform Console][developer-console] project with the Common Protos [API enabled][enable-api].
+You will need to [enable billing][enable-billing] to use Google Common Protos.
+[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
+[installing the Google Cloud SDK][cloud-sdk] and running the following commands in command line:
+`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
+
+### Installation and setup
+
+You'll need to obtain the `proto-google-common-protos` library.  See the [Quickstart](#quickstart) section
+to add `proto-google-common-protos` as a dependency in your code.
+
+## About Common Protos
+
+
+[Common Protos][product-docs] Protobuf classes for Google's common protos.
+
+See the [Common Protos client library docs][javadocs] to learn how to
+use this Common Protos Client Library.
+
+
+
+
+
+
+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
+
+## Transport
+
+Common Protos uses gRPC for the transport layer.
+
+## Supported Java Versions
+
+Java 8 or above is required for using this client.
+
+Google's Java client libraries,
+[Google Cloud Client Libraries][cloudlibs]
+and
+[Google Cloud API Libraries][apilibs],
+follow the
+[Oracle Java SE support roadmap][oracle]
+(see the Oracle Java SE Product Releases section).
+
+### For new development
+
+In general, new feature development occurs with support for the lowest Java
+LTS version covered by  Oracle's Premier Support (which typically lasts 5 years
+from initial General Availability). If the minimum required JVM for a given
+library is changed, it is accompanied by a [semver][semver] major release.
+
+Java 11 and (in September 2021) Java 17 are the best choices for new
+development.
+
+### Keeping production systems current
+
+Google tests its client libraries with all current LTS versions covered by
+Oracle's Extended Support (which typically lasts 8 years from initial
+General Availability).
+
+#### Legacy support
+
+Google's client libraries support legacy versions of Java runtimes with long
+term stable libraries that don't receive feature updates on a best efforts basis
+as it may not be possible to backport all patches.
+
+Google provides updates on a best efforts basis to apps that continue to use
+Java 7, though apps might need to upgrade to current versions of the library
+that supports their JVM.
+
+#### Where to find specific information
+
+The latest versions and the supported Java versions are identified on
+the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
+and on [google-cloud-java][g-c-j].

   /**
    *
    *
    * 
            * A definition of a client library method signature.
+   *
    * In client libraries, each proto RPC corresponds to one or more methods
    * which the end user is able to call, and calls the underlying RPC.
    * Normally, this method receives a single argument (a struct or instance
    * corresponding to the RPC request object). Defining this field will
    * add one or more overloads providing flattened or simpler method signatures
    * in some languages.
+   *
    * The fields on the method signature are provided as a comma-separated
    * string.
+   *
    * For example, the proto RPC and annotation:
-   *   rpc CreateSubscription(CreateSubscriptionRequest)
-   *       returns (Subscription) {
-   *     option (google.api.method_signature) = "name,topic";
-   *   }
+   *
+   * rpc CreateSubscription(CreateSubscriptionRequest)
+   * returns (Subscription) {
+   * option (google.api.method_signature) = "name,topic";
+   * }
+   *
    * Would add the following Java overload (in addition to the method accepting
    * the request object):
-   *   public final Subscription createSubscription(String name, String topic)
+   *
+   * public final Subscription createSubscription(String name, String topic)
+   *
    * The following backwards-compatibility guidelines apply:
-   *   * Adding this annotation to an unannotated method is backwards
-   *     compatible.
-   *   * Adding this annotation to a method which already has existing
-   *     method signature annotations is backwards compatible if and only if
-   *     the new method signature annotation is last in the sequence.
-   *   * Modifying or removing an existing method signature annotation is
-   *     a breaking change.
-   *   * Re-ordering existing method signature annotations is a breaking
-   *     change.

+ * gRPC Transcoding
+ *
  * gRPC Transcoding is a feature for mapping between a gRPC method and one or
  * more HTTP REST endpoints. It allows developers to build a single API service
  * that supports both gRPC APIs and REST APIs. Many systems, including [Google

  * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
  * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
  * and use it for large scale production services.
+ *
  * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
  * how different portions of the gRPC request message are mapped to the URL
  * path, URL query parameters, and HTTP request body. It also controls how the
  * gRPC response message is mapped to the HTTP response body. `HttpRule` is
  * typically specified as an `google.api.http` annotation on the gRPC method.
+ *
  * Each mapping specifies a URL path template and an HTTP method. The path
  * template may refer to one or more fields in the gRPC request message, as long
  * as each field is a non-repeated field with a primitive (non-message) type.
  * The path template controls how fields of the request message are mapped to
  * the URL path.
+ *
  * Example:
- *     service Messaging {
- *       rpc GetMessage(GetMessageRequest) returns (Message) {
- *         option (google.api.http) = {
- *             get: "/v1/{name=messages/*}"
- *         };
- *       }
- *     }
- *     message GetMessageRequest {
- *       string name = 1; // Mapped to URL path.
- *     }
- *     message Message {
- *       string text = 1; // The resource content.
- *     }
+ *
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/{name=messages/*}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * string name = 1; // Mapped to URL path.
+ * }
+ * message Message {
+ * string text = 1; // The resource content.
+ * }
+ *
  * This enables an HTTP REST to gRPC mapping as below:
- * HTTP | gRPC
- * -----|-----
- * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+ *
+ * - HTTP: `GET /v1/messages/123456`
+ * - gRPC: `GetMessage(name: "messages/123456")`
+ *
  * Any fields in the request message which are not bound by the path template
  * automatically become HTTP query parameters if there is no HTTP request body.
  * For example:
- *     service Messaging {
- *       rpc GetMessage(GetMessageRequest) returns (Message) {
- *         option (google.api.http) = {
- *             get:"/v1/messages/{message_id}"
- *         };
- *       }
- *     }
- *     message GetMessageRequest {
- *       message SubMessage {
- *         string subfield = 1;
- *       }
- *       string message_id = 1; // Mapped to URL path.
- *       int64 revision = 2;    // Mapped to URL query parameter `revision`.
- *       SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
- *     }
+ *
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get:"/v1/messages/{message_id}"
+ * };
+ * }
+ * }
+ * message GetMessageRequest {
+ * message SubMessage {
+ * string subfield = 1;
+ * }
+ * string message_id = 1; // Mapped to URL path.
+ * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+ * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+ * }
+ *
  * This enables a HTTP JSON to RPC mapping as below:
- * HTTP | gRPC
- * -----|-----
- * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
- * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
- * "foo"))`
+ *
+ * - HTTP: `GET /v1/messages/123456?revision=2&sub.subfield=foo`
+ * - gRPC: `GetMessage(message_id: "123456" revision: 2 sub:
+ * SubMessage(subfield: "foo"))`
+ *
  * Note that fields which are mapped to URL query parameters must have a
  * primitive type or a repeated primitive type or a non-repeated message type.
  * In the case of a repeated type, the parameter can be repeated in the URL
  * as `...?param=A&param=B`. In the case of a message type, each field of the
  * message is mapped to a separate parameter, such as
  * `...?foo.a=A&foo.b=B&foo.c=C`.
+ *
  * For HTTP methods that allow a request body, the `body` field
  * specifies the mapping. Consider a REST update method on the
  * message resource collection:
- *     service Messaging {
- *       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
- *         option (google.api.http) = {
- *           patch: "/v1/messages/{message_id}"
- *           body: "message"
- *         };
- *       }
- *     }
- *     message UpdateMessageRequest {
- *       string message_id = 1; // mapped to the URL
- *       Message message = 2;   // mapped to the body
- *     }
+ *
+ * service Messaging {
+ * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "message"
+ * };
+ * }
+ * }
+ * message UpdateMessageRequest {
+ * string message_id = 1; // mapped to the URL
+ * Message message = 2;   // mapped to the body
+ * }
+ *
  * The following HTTP JSON to RPC mapping is enabled, where the
  * representation of the JSON in the request body is determined by
  * protos JSON encoding:
- * HTTP | gRPC
- * -----|-----
- * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
- * "123456" message { text: "Hi!" })`
+ *
+ * - HTTP: `PATCH /v1/messages/123456 { "text": "Hi!" }`
+ * - gRPC: `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
+ *
  * The special name `*` can be used in the body mapping to define that
  * every field not bound by the path template should be mapped to the
  * request body.  This enables the following alternative definition of
  * the update method:
- *     service Messaging {
- *       rpc UpdateMessage(Message) returns (Message) {
- *         option (google.api.http) = {
- *           patch: "/v1/messages/{message_id}"
- *           body: "*"
- *         };
- *       }
- *     }
- *     message Message {
- *       string message_id = 1;
- *       string text = 2;
- *     }
+ *
+ * service Messaging {
+ * rpc UpdateMessage(Message) returns (Message) {
+ * option (google.api.http) = {
+ * patch: "/v1/messages/{message_id}"
+ * body: "*"
+ * };
+ * }
+ * }
+ * message Message {
+ * string message_id = 1;
+ * string text = 2;
+ * }
+ *
+ *
  * The following HTTP JSON to RPC mapping is enabled:
- * HTTP | gRPC
- * -----|-----
- * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
- * "123456" text: "Hi!")`
+ *
+ * - HTTP: `PATCH /v1/messages/123456 { "text": "Hi!" }`
+ * - gRPC: `UpdateMessage(message_id: "123456" text: "Hi!")`
+ *
  * Note that when using `*` in the body mapping, it is not possible to
  * have HTTP parameters, as all fields not bound by the path end in
  * the body. This makes this option more rarely used in practice when
  * defining REST APIs. The common usage of `*` is in custom methods
  * which don't use the URL at all for transferring data.
+ *
  * It is possible to define multiple HTTP methods for one RPC by using
  * the `additional_bindings` option. Example:
- *     service Messaging {
- *       rpc GetMessage(GetMessageRequest) returns (Message) {
- *         option (google.api.http) = {
- *           get: "/v1/messages/{message_id}"
- *           additional_bindings {
- *             get: "/v1/users/{user_id}/messages/{message_id}"
- *           }
- *         };
- *       }
- *     }
- *     message GetMessageRequest {
- *       string message_id = 1;
- *       string user_id = 2;
- *     }
+ *
+ * service Messaging {
+ * rpc GetMessage(GetMessageRequest) returns (Message) {
+ * option (google.api.http) = {
+ * get: "/v1/messages/{message_id}"
+ * additional_bindings {
+ * get: "/v1/users/{user_id}/messages/{message_id}"
+ * }

- * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
- * "123456")`
- * ## Rules for HTTP mapping
+ *
+ * - HTTP: `GET /v1/messages/123456`
+ * - gRPC: `GetMessage(message_id: "123456")`
+ *

+ *
+ * Rules for HTTP mapping
+ *
  * 1. Leaf request fields (recursive expansion nested messages in the request
- *    message) are classified into three categories:
- *    - Fields referred by the path template. They are passed via the URL path.
- *    - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
- *      request body.
- *    - All other fields are passed via the URL query parameters, and the
- *      parameter name is the field path in the request message. A repeated
- *      field can be represented as multiple query parameters under the same
- *      name.
- *  2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
- *     are passed via URL path and HTTP request body.
- *  3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
- *     fields are passed via URL path and URL query parameters.
- * ### Path template syntax
- *     Template = "/" Segments [ Verb ] ;
- *     Segments = Segment { "/" Segment } ;
- *     Segment  = "*" | "**" | LITERAL | Variable ;

+ * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+ * FieldPath = IDENT { "." IDENT } ;
+ * Verb     = ":" LITERAL ;
+ *
  * The syntax `*` matches a single URL path segment. The syntax `**` matches
  * zero or more URL path segments, which must be the last part of the URL path
  * except the `Verb`.
+ *
  * The syntax `Variable` matches part of the URL path as specified by its
  * template. A variable template must not contain other variables. If a variable
  * matches a single path segment, its template may be omitted, e.g. `{var}`
  * is equivalent to `{var=*}`.
+ *
  * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
  * contains any reserved character, such characters should be percent-encoded
  * before the matching.
+ *
  * If a variable contains exactly one path segment, such as `"{var}"` or

    * gRPC Transcoding is a feature for mapping between a gRPC method and one or

    * Gateway](https://github.com/grpc-ecosystem/grpc-gateway),
    * and [Envoy](https://github.com/envoyproxy/envoy) proxy support this feature
    * and use it for large scale production services.
+   *
    * `HttpRule` defines the schema of the gRPC/REST mapping. The mapping specifies
    * how different portions of the gRPC request message are mapped to the URL
    * path, URL query parameters, and HTTP request body. It also controls how the
    * gRPC response message is mapped to the HTTP response body. `HttpRule` is
    * typically specified as an `google.api.http` annotation on the gRPC method.
+   *
    * Each mapping specifies a URL path template and an HTTP method. The path
    * template may refer to one or more fields in the gRPC request message, as long
    * as each field is a non-repeated field with a primitive (non-message) type.
    * The path template controls how fields of the request message are mapped to
    * the URL path.
+   *
    * Example:
-   *     service Messaging {
-   *       rpc GetMessage(GetMessageRequest) returns (Message) {
-   *         option (google.api.http) = {
-   *             get: "/v1/{name=messages/*}"
-   *         };
-   *       }
-   *     }
-   *     message GetMessageRequest {
-   *       string name = 1; // Mapped to URL path.
-   *     }
-   *     message Message {
-   *       string text = 1; // The resource content.
-   *     }
+   *
+   * service Messaging {
+   * rpc GetMessage(GetMessageRequest) returns (Message) {
+   * option (google.api.http) = {
+   * get: "/v1/{name=messages/*}"
+   * };
+   * }
+   * }
+   * message GetMessageRequest {
+   * string name = 1; // Mapped to URL path.
+   * }
+   * message Message {
+   * string text = 1; // The resource content.
+   * }
+   *
    * This enables an HTTP REST to gRPC mapping as below:
-   * HTTP | gRPC
-   * -----|-----
-   * `GET /v1/messages/123456`  | `GetMessage(name: "messages/123456")`
+   *
+   * - HTTP: `GET /v1/messages/123456`
+   * - gRPC: `GetMessage(name: "messages/123456")`
+   *
    * Any fields in the request message which are not bound by the path template
    * automatically become HTTP query parameters if there is no HTTP request body.
    * For example:
-   *     service Messaging {
-   *       rpc GetMessage(GetMessageRequest) returns (Message) {
-   *         option (google.api.http) = {
-   *             get:"/v1/messages/{message_id}"
-   *         };
-   *       }
-   *     }
-   *     message GetMessageRequest {
-   *       message SubMessage {
-   *         string subfield = 1;
-   *       }
-   *       string message_id = 1; // Mapped to URL path.
-   *       int64 revision = 2;    // Mapped to URL query parameter `revision`.
-   *       SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
-   *     }
+   *
+   * service Messaging {
+   * rpc GetMessage(GetMessageRequest) returns (Message) {
+   * option (google.api.http) = {
+   * get:"/v1/messages/{message_id}"
+   * };
+   * }
+   * }
+   * message GetMessageRequest {
+   * message SubMessage {
+   * string subfield = 1;
+   * }
+   * string message_id = 1; // Mapped to URL path.
+   * int64 revision = 2;    // Mapped to URL query parameter `revision`.
+   * SubMessage sub = 3;    // Mapped to URL query parameter `sub.subfield`.
+   * }
+   *
    * This enables a HTTP JSON to RPC mapping as below:
-   * HTTP | gRPC
-   * -----|-----
-   * `GET /v1/messages/123456?revision=2&sub.subfield=foo` |
-   * `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield:
-   * "foo"))`
+   *
+   * - HTTP: `GET /v1/messages/123456?revision=2&sub.subfield=foo`
+   * - gRPC: `GetMessage(message_id: "123456" revision: 2 sub:
+   * SubMessage(subfield: "foo"))`
+   *
    * Note that fields which are mapped to URL query parameters must have a
    * primitive type or a repeated primitive type or a non-repeated message type.
    * In the case of a repeated type, the parameter can be repeated in the URL
    * as `...?param=A&param=B`. In the case of a message type, each field of the
    * message is mapped to a separate parameter, such as
    * `...?foo.a=A&foo.b=B&foo.c=C`.
+   *
    * For HTTP methods that allow a request body, the `body` field
    * specifies the mapping. Consider a REST update method on the
    * message resource collection:
-   *     service Messaging {
-   *       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
-   *         option (google.api.http) = {
-   *           patch: "/v1/messages/{message_id}"
-   *           body: "message"
-   *         };
-   *       }
-   *     }
-   *     message UpdateMessageRequest {
-   *       string message_id = 1; // mapped to the URL
-   *       Message message = 2;   // mapped to the body
-   *     }
+   *
+   * service Messaging {
+   * rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
+   * option (google.api.http) = {
+   * patch: "/v1/messages/{message_id}"
+   * body: "message"
+   * };
+   * }
+   * }
+   * message UpdateMessageRequest {
+   * string message_id = 1; // mapped to the URL
+   * Message message = 2;   // mapped to the body
+   * }
+   *
    * The following HTTP JSON to RPC mapping is enabled, where the
    * representation of the JSON in the request body is determined by
    * protos JSON encoding:
-   * HTTP | gRPC
-   * -----|-----
-   * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-   * "123456" message { text: "Hi!" })`
+   *
+   * - HTTP: `PATCH /v1/messages/123456 { "text": "Hi!" }`
+   * - gRPC: `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
+   *
    * The special name `*` can be used in the body mapping to define that
    * every field not bound by the path template should be mapped to the
    * request body.  This enables the following alternative definition of
    * the update method:
-   *     service Messaging {
-   *       rpc UpdateMessage(Message) returns (Message) {
-   *         option (google.api.http) = {
-   *           patch: "/v1/messages/{message_id}"
-   *           body: "*"
-   *         };
-   *       }
-   *     }
-   *     message Message {
-   *       string message_id = 1;
-   *       string text = 2;
-   *     }
+   *
+   * service Messaging {
+   * rpc UpdateMessage(Message) returns (Message) {
+   * option (google.api.http) = {
+   * patch: "/v1/messages/{message_id}"
+   * body: "*"
+   * };
+   * }
+   * }
+   * message Message {
+   * string message_id = 1;
+   * string text = 2;
+   * }
+   *
+   *
    * The following HTTP JSON to RPC mapping is enabled:
-   * HTTP | gRPC
-   * -----|-----
-   * `PATCH /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id:
-   * "123456" text: "Hi!")`
+   *
+   * - HTTP: `PATCH /v1/messages/123456 { "text": "Hi!" }`
+   * - gRPC: `UpdateMessage(message_id: "123456" text: "Hi!")`
+   *
    * Note that when using `*` in the body mapping, it is not possible to
    * have HTTP parameters, as all fields not bound by the path end in
    * the body. This makes this option more rarely used in practice when
    * defining REST APIs. The common usage of `*` is in custom methods
    * which don't use the URL at all for transferring data.
+   *
    * It is possible to define multiple HTTP methods for one RPC by using
    * the `additional_bindings` option. Example:
-   *     service Messaging {
-   *       rpc GetMessage(GetMessageRequest) returns (Message) {
-   *         option (google.api.http) = {
-   *           get: "/v1/messages/{message_id}"
-   *           additional_bindings {
-   *             get: "/v1/users/{user_id}/messages/{message_id}"
-   *           }
-   *         };
-   *       }
-   *     }
-   *     message GetMessageRequest {
-   *       string message_id = 1;
-   *       string user_id = 2;
-   *     }
+   *
+   * service Messaging {
+   * rpc GetMessage(GetMessageRequest) returns (Message) {
+   * option (google.api.http) = {
+   * get: "/v1/messages/{message_id}"
+   * additional_bindings {
+   * get: "/v1/users/{user_id}/messages/{message_id}"
+   * }
+   * };
+   * }
+   * }
+   * message GetMessageRequest {
+   * string message_id = 1;
+   * string user_id = 2;
+   * }
+   *
    * This enables the following two alternative HTTP JSON to RPC mappings:
-   * HTTP | gRPC
-   * -----|-----
-   * `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
-   * `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id:
-   * "123456")`
-   * ## Rules for HTTP mapping
+   *
+   * - HTTP: `GET /v1/messages/123456`
+   * - gRPC: `GetMessage(message_id: "123456")`
+   *
+   * - HTTP: `GET /v1/users/me/messages/123456`
+   * - gRPC: `GetMessage(user_id: "me" message_id: "123456")`
+   *
+   * Rules for HTTP mapping
+   *
    * 1. Leaf request fields (recursive expansion nested messages in the request
-   *    message) are classified into three categories:
-   *    - Fields referred by the path template. They are passed via the URL path.
-   *    - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They are passed via the HTTP
-   *      request body.
-   *    - All other fields are passed via the URL query parameters, and the
-   *      parameter name is the field path in the request message. A repeated
-   *      field can be represented as multiple query parameters under the same
-   *      name.
-   *  2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL query parameter, all fields
-   *     are passed via URL path and HTTP request body.
-   *  3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP request body, all
-   *     fields are passed via URL path and URL query parameters.
-   * ### Path template syntax
-   *     Template = "/" Segments [ Verb ] ;
-   *     Segments = Segment { "/" Segment } ;
-   *     Segment  = "*" | "**" | LITERAL | Variable ;
-   *     Variable = "{" FieldPath [ "=" Segments ] "}" ;
-   *     FieldPath = IDENT { "." IDENT } ;
-   *     Verb     = ":" LITERAL ;

+   * - Fields referred by the path template. They are passed via the URL path.
+   * - Fields referred by the [HttpRule.body][google.api.HttpRule.body]. They
+   * are passed via the HTTP
+   * request body.
+   * - All other fields are passed via the URL query parameters, and the
+   * parameter name is the field path in the request message. A repeated
+   * field can be represented as multiple query parameters under the same
+   * name.
+   * 2. If [HttpRule.body][google.api.HttpRule.body] is "*", there is no URL
+   * query parameter, all fields
+   * are passed via URL path and HTTP request body.
+   * 3. If [HttpRule.body][google.api.HttpRule.body] is omitted, there is no HTTP
+   * request body, all
+   * fields are passed via URL path and URL query parameters.
+   *
+   * Path template syntax
+   *
+   * Template = "/" Segments [ Verb ] ;
+   * Segments = Segment { "/" Segment } ;
+   * Segment  = "*" | "**" | LITERAL | Variable ;
+   * Variable = "{" FieldPath [ "=" Segments ] "}" ;
+   * FieldPath = IDENT { "." IDENT } ;
+   * Verb     = ":" LITERAL ;
+   *
    * The syntax `*` matches a single URL path segment. The syntax `**` matches
    * zero or more URL path segments, which must be the last part of the URL path
    * except the `Verb`.
+   *
    * The syntax `Variable` matches part of the URL path as specified by its
    * template. A variable template must not contain other variables. If a variable
    * matches a single path segment, its template may be omitted, e.g. `{var}`
    * is equivalent to `{var=*}`.
+   *
    * The syntax `LITERAL` matches literal text in the URL path. If the `LITERAL`
    * contains any reserved character, such characters should be percent-encoded
    * before the matching.
+   *
    * If a variable contains exactly one path segment, such as `"{var}"` or

          * A simple descriptor of a resource type.
+ *
  * ResourceDescriptor annotates a resource message (either by means of a
  * protobuf annotation or use in the service config), and associates the
  * resource's schema, the resource type, and the pattern of the resource name.
+ *
  * Example:
- *     message Topic {
- *       // Indicates this message defines a resource schema.
- *       // Declares the resource type in the format of {service}/{kind}.
- *       // For Kubernetes resources, the format is {api group}/{kind}.
- *       option (google.api.resource) = {
- *         type: "pubsub.googleapis.com/Topic"
- *         pattern: "projects/{project}/topics/{topic}"
- *       };
- *     }

+ * message Topic {
+ * // Indicates this message defines a resource schema.
+ * // Declares the resource type in the format of {service}/{kind}.

+ * option (google.api.resource) = {
+ * type: "pubsub.googleapis.com/Topic"
+ * pattern: "projects/{project}/topics/{topic}"
+ * };
+ * }
+ *
  * The ResourceDescriptor Yaml config will look like:
- *     resources:
- *     - type: "pubsub.googleapis.com/Topic"
- *       pattern: "projects/{project}/topics/{topic}"
+ *
+ * resources:
+ * - type: "pubsub.googleapis.com/Topic"
+ * pattern: "projects/{project}/topics/{topic}"
+ *
  * Sometimes, resources have multiple patterns, typically because they can
  * live under multiple parents.
+ *
  * Example:
- *     message LogEntry {
- *       option (google.api.resource) = {
- *         type: "logging.googleapis.com/LogEntry"
- *         pattern: "projects/{project}/logs/{log}"

- *         pattern: "billingAccounts/{billing_account}/logs/{log}"

  * An attribute is a piece of metadata that describes an activity on a network

  * an HTTP response.
+ *
  * Each attribute has a type and a name, which is logically defined as

  * attribute type, and the field path becomes the attribute name. For example,
  * the attribute `source.ip` maps to field `AttributeContext.source.ip`.

    * An attribute is a piece of metadata that describes an activity on a network
    * service. For example, the size of an HTTP request, or the status code of
    * an HTTP response.
+   *
    * Each attribute has a type and a name, which is logically defined as
    * a proto message field in `AttributeContext`. The field type becomes the
    * attribute type, and the field path becomes the attribute name. For example,
    * the attribute `source.ip` maps to field `AttributeContext.source.ip`.
+   *
    * This message definition is guaranteed not to have any wire breaking change.
    * So you can use it directly for passing attributes across different systems.
+   *
    * NOTE: Different system may generate different subset of attributes. Please
    * verify the system specification before relying on an attribute generated
    * a system.

    * The string representation consists of an optional sign, `+` (`U+002B`)
    * or `-` (`U+002D`), followed by a sequence of zero or more decimal digits
    * ("the integer"), optionally followed by a fraction, optionally followed
    * by an exponent.
+   *
    * The fraction consists of a decimal point followed by zero or more decimal
    * digits. The string must contain at least one digit in either the integer
    * or the fraction. The number formed by the sign, the integer and the
    * fraction is referred to as the significand.
+   *
    * The exponent consists of the character `e` (`U+0065`) or `E` (`U+0045`)
    * followed by one or more decimal digits.
+   *
    * Services **should** normalize decimal values before storing them by:
-   *   - Removing an explicitly-provided `+` sign (`+2.5` -> `2.5`).
-   *   - Replacing a zero-length integer value with `0` (`.5` -> `0.5`).
-   *   - Coercing the exponent character to lower-case (`2.5E8` -> `2.5e8`).
-   *   - Removing an explicitly-provided zero exponent (`2.5e0` -> `2.5`).
+   *
+   * - Removing an explicitly-provided `+` sign (`+2.5` -> `2.5`).

+   * - Removing an explicitly-provided zero exponent (`2.5e0` -> `2.5`).
+   *
    * Services **may** perform additional normalization based on its own needs
    * and the internal decimal implementation selected, such as shifting the
    * decimal point and exponent value together (example: `2.5e-1` <-> `0.25`).
    * Additionally, services **may** preserve trailing zeroes in the fraction
    * to indicate increased precision, but are not required to do so.
+   *
    * Note that only the `.` character is supported to divide the integer
    * and the fraction; `,` **should not** be supported regardless of locale.
    * Additionally, thousand separators **should not** be supported. If a
    * service does support them, values **must** be normalized.

-   *     Sign = '+' | '-';
-   *     Significand =

-   *     Exponent = ('e' | 'E') [Sign] Digits;
-   *     Digits = { '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' };

+   * Digits = { '0' | '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' };
+   *
    * Services **should** clearly document the range of supported values, the
    * maximum supported precision (total number of digits), and, if applicable,
    * the scale (number of digits after the decimal point), as well as how it
    * behaves when receiving out-of-bounds values.
+   *
    * Services **may** choose to accept values passed as input even when the
    * value has a higher precision or scale than the service supports, and
    * **should** round the value to fit the supported scale. Alternatively, the
    * service **may** error with `400 Bad Request` (`INVALID_ARGUMENT` in gRPC)

  * A quaternion is defined as the quotient of two directed lines in a
  * three-dimensional space or equivalently as the quotient of two Euclidean
  * vectors (https://en.wikipedia.org/wiki/Quaternion).
+ *
  * Quaternions are often used in calculations involving three-dimensional
  * rotations (https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation),
  * as they provide greater mathematical robustness by avoiding the gimbal lock
  * problems that can be encountered when using Euler angles
  * (https://en.wikipedia.org/wiki/Gimbal_lock).

  * Quaternions are generally represented in this form:
- *     w + xi + yj + zk
+ *
+ * w + xi + yj + zk
+ *
  * where x, y, z, and w are real numbers, and i, j, and k are three imaginary
  * numbers.
+ *
  * Our naming choice `(x, y, z, w)` comes from the desire to avoid confusion for
  * those interested in the geometric properties of the quaternion in the 3D
  * Cartesian space. Other texts often use alternative names or subscripts, such
  * as `(a, b, c, d)`, `(1, i, j, k)`, or `(0, 1, 2, 3)`, which are perhaps
  * better suited for mathematical interpretations.
+ *
  * To avoid any confusion, as well as to maintain compatibility with a large
  * number of software libraries, the quaternions represented using the protocol
  * buffer below *must* follow the Hamilton convention, which defines `ij = k`
  * (i.e. a right-handed algebra), and therefore:
- *     i^2 = j^2 = k^2 = ijk = −1
- *     ij = −ji = k
- *     jk = −kj = i
- *     ki = −ik = j

+ * ij = −ji = k
+ * jk = −kj = i

  * Please DO NOT use this to represent quaternions that follow the JPL
  * convention, or any of the other quaternion flavors out there.

- *   - Quaternion norm (or magnitude): `sqrt(x^2 + y^2 + z^2 + w^2)`.
- *   - Unit (or normalized) quaternion: a quaternion whose norm is 1.

-# Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as
-contributors and maintainers pledge to making participation in our project and
-our community a harassment-free experience for everyone, regardless of age, body
-size, disability, ethnicity, gender identity and expression, level of
-experience, education, socio-economic status, nationality, personal appearance,
-race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment
-include:
-
-*   Using welcoming and inclusive language
-*   Being respectful of differing viewpoints and experiences
-*   Gracefully accepting constructive criticism
-*   Focusing on what is best for the community
-*   Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-*   The use of sexualized language or imagery and unwelcome sexual attention or
-    advances
-*   Trolling, insulting/derogatory comments, and personal or political attacks
-*   Public or private harassment
-*   Publishing others' private information, such as a physical or electronic
-    address, without explicit permission
-*   Other conduct which could reasonably be considered inappropriate in a
-    professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable
-behavior and are expected to take appropriate and fair corrective action in
-response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, or to ban temporarily or permanently any
-contributor for other behaviors that they deem inappropriate, threatening,
-offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. Examples of
-representing a project or community include using an official project e-mail
-address, posting via an official social media account, or acting as an appointed
-representative at an online or offline event. Representation of a project may be
-further defined and clarified by project maintainers.
-
-This Code of Conduct also applies outside the project spaces when the Project
-Steward has a reasonable belief that an individual's behavior may have a
-negative impact on the project or its community.
-
-## Conflict Resolution
-
-We do not believe that all conflict is bad; healthy debate and disagreement
-often yield positive results. However, it is never okay to be disrespectful or
-to engage in behavior that violates the project’s code of conduct.
-
-If you see someone violating the code of conduct, you are encouraged to address
-the behavior directly with those involved. Many issues can be resolved quickly
-and easily, and this gives people more control over the outcome of their
-dispute. If you are unable to resolve the matter for any reason, or if the
-behavior is threatening or harassing, report it. We are dedicated to providing
-an environment where participants feel welcome and safe.
-
-Reports should be directed to *googleapis-stewards@google.com*, the
-Project Steward(s) for *Google Cloud Client Libraries*. It is the Project Steward’s duty to
-receive and address reported violations of the code of conduct. They will then
-work with a committee consisting of representatives from the Open Source
-Programs Office and the Google Open Source Strategy team. If for any reason you
-are uncomfortable reaching out to the Project Steward, please email
-opensource@google.com.
-
-We will investigate every complaint, but you may not receive a direct response.
-We will use our discretion in determining when and how to follow up on reported
-incidents, which may range from not taking action to permanent expulsion from
-the project and project-sponsored spaces. We will notify the accused of the
-report and provide them an opportunity to discuss it before any action is taken.
-The identity of the reporter will be omitted from the details of the report
-supplied to the accused. In potentially harmful situations, such as ongoing
-harassment or threats to anyone's safety, we may take action without notice.
-
-## Attribution
-
-This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
-available at
-https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

-# How to Contribute
-
-We'd love to accept your patches and contributions to this project. There are
-just a few small guidelines you need to follow.
-
-## Contributor License Agreement
-
-Contributions to this project must be accompanied by a Contributor License
-Agreement. You (or your employer) retain the copyright to your contribution;
-this simply gives us permission to use and redistribute your contributions as
-part of the project. Head over to  to see
-your current agreements on file or to sign a new one.
-
-You generally only need to submit a CLA once, so if you've already submitted one
-(even if it was for a different project), you probably don't need to do it
-again.
-
-## Code reviews
-
-All submissions, including submissions by project members, require review. We
-use GitHub pull requests for this purpose. Consult
-[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
-information on using pull requests.
-
-## Community Guidelines
-
-This project follows
-[Google's Open Source Community Guidelines](https://opensource.google.com/conduct/).
-
-## Building the project
-
-To build, package, and run all unit tests run the command
-
-```
-mvn clean verify
-```
-
-### Running Integration tests
-
-To include integration tests when building the project, you need access to
-a GCP Project with a valid service account. 
-
-For instructions on how to generate a service account and corresponding
-credentials JSON see: [Creating a Service Account][1].
-
-Then run the following to build, package, run all unit tests and run all
-integration tests.
-
-```bash
-export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
-mvn -Penable-integration-tests clean verify
-```
-
-## Code Samples
-
-All code samples must be in compliance with the [java sample formatting guide][3].
-Code Samples must be bundled in separate Maven modules.
-
-The samples must be separate from the primary project for a few reasons:
-1. Primary projects have a minimum Java version of Java 8 whereas samples can have
-   Java version of Java 11. Due to this we need the ability to
-   selectively exclude samples from a build run.
-2. Many code samples depend on external GCP services and need
-   credentials to access the service.
-3. Code samples are not released as Maven artifacts and must be excluded from 
-   release builds.
-   
-### Building
-
-```bash
-mvn clean verify
-```
-
-Some samples require access to GCP services and require a service account:
-
-```bash
-export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
-mvn clean verify
-```
-
-### Code Formatting
-
-Code in this repo is formatted with
-[google-java-format](https://github.com/google/google-java-format).
-To run formatting on your project, you can run:
-```
-mvn com.coveo:fmt-maven-plugin:format
-```

-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

          * An Identity and Access Management (IAM) policy, which specifies access
  * controls for Google Cloud resources.
+ *
+ *
  * A `Policy` is a collection of `bindings`. A `binding` binds one or more
  * `members`, or principals, to a single `role`. Principals can be user
  * accounts, service accounts, Google groups, and domains (such as G Suite). A
  * `role` is a named list of permissions; each `role` can be an IAM predefined
  * role or a user-created custom role.
+ *
  * For some types of Google Cloud resources, a `binding` can also specify a
  * `condition`, which is a logical expression that allows access to a resource
  * only if the expression evaluates to `true`. A condition can add constraints
  * based on attributes of the request, the resource, or both. To learn which
  * resources support conditions in their IAM policies, see the
- * [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).

    * 
            * An Identity and Access Management (IAM) policy, which specifies access
    * controls for Google Cloud resources.
+   *
+   *
    * A `Policy` is a collection of `bindings`. A `binding` binds one or more
    * `members`, or principals, to a single `role`. Principals can be user
    * accounts, service accounts, Google groups, and domains (such as G Suite). A
    * `role` is a named list of permissions; each `role` can be an IAM predefined
    * role or a user-created custom role.
+   *
    * For some types of Google Cloud resources, a `binding` can also specify a
    * `condition`, which is a logical expression that allows access to a resource
    * only if the expression evaluates to `true`. A condition can add constraints
    * based on attributes of the request, the resource, or both. To learn which
    * resources support conditions in their IAM policies, see the

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: This service is used to test that GAPICs implement various REST-related
+ * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
+ * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
+ * received by clients can be round-tripped correctly.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ComplianceClient complianceClient = ComplianceClient.create()) {
+ *   RepeatRequest request =
+ *       RepeatRequest.newBuilder()
+ *           .setName("name3373707")
+ *           .setInfo(ComplianceData.newBuilder().build())
+ *           .setServerVerify(true)
+ *           .setIntendedBindingUri("intendedBindingUri780142386")
+ *           .setFInt32(-1143775883)
+ *           .setFInt64(-1143775788)
+ *           .setFDouble(-1239459382)
+ *           .setPInt32(-858673665)
+ *           .setPInt64(-858673570)
+ *           .setPDouble(-991225216)
+ *           .build();
+ *   RepeatResponse response = complianceClient.repeatDataBody(request);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the ComplianceClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

         RepeatDataBody
         This method echoes the ComplianceData request. This method exercises sending the entire request object in the REST body.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

         GetEnum
         This method requests an enum value from the server. Depending on the contents of EnumRequest, the enum value returned will be a known enum declared in the .proto file, or a made-up enum value the is unknown to the client. To verify that clients can round-trip unknown enum values they receive, use the response from this RPC as the request to VerifyEnum()
+ * 
          The values of enums sent by the server when a known or unknown value is requested will be the same within a single Showcase server run (this is needed for VerifyEnum() to work) but are not guaranteed to be the same across separate Showcase server runs.

         VerifyEnum
         This method is used to verify that clients can round-trip enum values, which is particularly important for unknown enum values over REST. VerifyEnum() verifies that its request, which is presumably the response that the client previously got to a GetEnum(), contains the correct data. If so, it responds with the same EnumResponse; otherwise, the RPC errors.
+ * 
          This works because the values of enums sent by the server when a known or unknown value is requested will be the same within a single Showcase server run, although they are not guaranteed to be the same across separate Showcase server runs.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of ComplianceSettings to
+ * create(). For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings =
+ *     ComplianceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings =
+ *     ComplianceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings = ComplianceSettings.newHttpJsonBuilder().build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link ComplianceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of repeatDataBody:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings.Builder complianceSettingsBuilder = ComplianceSettings.newBuilder();
+ * complianceSettingsBuilder
+ *     .repeatDataBodySettings()
+ *     .setRetrySettings(
+ *         complianceSettingsBuilder
+ *             .repeatDataBodySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * ComplianceSettings complianceSettings = complianceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+/**
+ * Service Description: This service is used showcase the four main types of rpcs - unary, server
+ * side streaming, client side streaming, and bidirectional streaming. This service also exposes
+ * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
+ * metadata key on any method to have the values echoed in the response trailers. Set the
+ * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
+ * headers.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (EchoClient echoClient = EchoClient.create()) {
+ *   EchoRequest request =
+ *       EchoRequest.newBuilder()
+ *           .setSeverity(Severity.forNumber(0))
+ *           .setHeader("header-1221270899")
+ *           .setOtherHeader("otherHeader-2026585667")
+ *           .setRequestId("requestId693933066")
+ *           .setOtherRequestId("otherRequestId1248995034")
+ *           .build();
+ *   EchoResponse response = echoClient.echo(request);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the EchoClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

        Methods
        MethodDescriptionMethod Variants
         Echo
         This method simply echoes the request. This method showcases unary RPCs.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  echo(EchoRequest request)
+ *      
        
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  echoCallable()
+ *      
        
+ *       
         EchoErrorDetails
         This method returns error details in a repeated "google.protobuf.Any" field. This method showcases handling errors thus encoded, particularly over REST transport. Note that GAPICs only allow the type "google.protobuf.Any" for field paths ending in "error.details", and, at run-time, the actual types for these fields must be one of the types in google/rpc/error_details.proto.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  echoErrorDetails(EchoErrorDetailsRequest request)
+ *

+ *      
        
+ *       
         FailEchoWithDetails
         This method always fails with a gRPC "Aborted" error status that contains multiple error details.  These include one instance of each of the standard ones in error_details.proto (https://github.com/googleapis/googleapis/blob/master/google/rpc/error_details.proto) plus a custom, Showcase-defined PoetryError. The intent of this RPC is to verify that GAPICs can process these various error details and surface them to the user in an idiomatic form.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *           
        •  chatCallable()
+ *      
        
+ *       
         PagedExpand

+ *       
         PagedExpandLegacy
         This is similar to the PagedExpand except that it uses max_results instead of page_size, as some legacy APIs still do. New APIs should NOT use this pattern.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
        
+ *       
         PagedExpandLegacyMapped
         This method returns a map containing lists of words that appear in the input, keyed by their initial character. The only words returned are the ones included in the current page, as determined by page_token and page_size, which both refer to the word indices in the input. This paging result consisting of a map of lists is a pattern used by some legacy APIs. New APIs should NOT use this pattern.

        Many parameters require resource names to be formatted in a particular way. To assist with

+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of EchoSettings to create(). For
+ * example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings =
+ *     EchoSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings = EchoSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings = EchoSettings.newHttpJsonBuilder().build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link EchoClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of echo:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * EchoSettings echoSettings = echoSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for wait:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * echoSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Service Description: A simple identity service.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (IdentityClient identityClient = IdentityClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String email = "email96619420";
+ *   User response = identityClient.createUser(displayName, email);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the IdentityClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

        •  testIamPermissions(TestIamPermissionsRequest request)

        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of IdentitySettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings identitySettings =
+ *     IdentitySettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * IdentityClient identityClient = IdentityClient.create(identitySettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings identitySettings =
+ *     IdentitySettings.newBuilder().setEndpoint(myEndpoint).build();
+ * IdentityClient identityClient = IdentityClient.create(identitySettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings identitySettings = IdentitySettings.newHttpJsonBuilder().build();
+ * IdentityClient identityClient = IdentityClient.create(identitySettings);
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link IdentityClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createUser:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings.Builder identitySettingsBuilder = IdentitySettings.newBuilder();
+ * identitySettingsBuilder
+ *     .createUserSettings()
+ *     .setRetrySettings(
+ *         identitySettingsBuilder
+ *             .createUserSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * IdentitySettings identitySettings = identitySettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+ * Service Description: A simple messaging service that implements chat rooms and profile posts.
+ *
+ * 
        This messaging service showcases the features that API clients generated by gapic-generators
+ * implement.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (MessagingClient messagingClient = MessagingClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String description = "description-1724546052";
+ *   Room response = messagingClient.createRoom(displayName, description);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the MessagingClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of MessagingSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings =
+ *     MessagingSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings =
+ *     MessagingSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings = MessagingSettings.newHttpJsonBuilder().build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);

+/**
+ * Settings class to configure an instance of {@link MessagingClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createRoom:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings.Builder messagingSettingsBuilder = MessagingSettings.newBuilder();
+ * messagingSettingsBuilder
+ *     .createRoomSettings()
+ *     .setRetrySettings(
+ *         messagingSettingsBuilder
+ *             .createRoomSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * MessagingSettings messagingSettings = messagingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for searchBlurbs:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings.Builder messagingSettingsBuilder = MessagingSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * messagingSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

        •  testIamPermissions(TestIamPermissionsRequest request)
+ *

        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of SequenceServiceSettings to
+ * create(). For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings sequenceServiceSettings =
+ *     SequenceServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * SequenceServiceClient sequenceServiceClient =
+ *     SequenceServiceClient.create(sequenceServiceSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings sequenceServiceSettings =
+ *     SequenceServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * SequenceServiceClient sequenceServiceClient =
+ *     SequenceServiceClient.create(sequenceServiceSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings sequenceServiceSettings =
+ *     SequenceServiceSettings.newHttpJsonBuilder().build();
+ * SequenceServiceClient sequenceServiceClient =
+ *     SequenceServiceClient.create(sequenceServiceSettings);

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link SequenceServiceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSequence:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings.Builder sequenceServiceSettingsBuilder =
+ *     SequenceServiceSettings.newBuilder();

+ *     .setRetrySettings(
+ *         sequenceServiceSettingsBuilder
+ *             .createSequenceSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+ *             .build());
+ * SequenceServiceSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of TestingSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings =
+ *     TestingSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings = TestingSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings = TestingSettings.newHttpJsonBuilder().build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link TestingClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSession:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings.Builder testingSettingsBuilder = TestingSettings.newBuilder();
+ * testingSettingsBuilder
+ *     .createSessionSettings()
+ *     .setRetrySettings(
+ *         testingSettingsBuilder
+ *             .createSessionSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * TestingSettings testingSettings = testingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+/**
+ * A client to Client Libraries Showcase API
+ *
+ * 
        The interfaces provided are listed below, along with usage samples.
+ *
+ * 
        ======================= ComplianceClient =======================
+ *
+ * 
        Service Description: This service is used to test that GAPICs implement various REST-related
+ * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
+ * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
+ * received by clients can be round-tripped correctly.
+ *
+ * 
        Sample for ComplianceClient:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ComplianceClient complianceClient = ComplianceClient.create()) {
+ *   RepeatRequest request =
+ *       RepeatRequest.newBuilder()
+ *           .setName("name3373707")
+ *           .setInfo(ComplianceData.newBuilder().build())
+ *           .setServerVerify(true)
+ *           .setIntendedBindingUri("intendedBindingUri780142386")
+ *           .setFInt32(-1143775883)
+ *           .setFInt64(-1143775788)
+ *           .setFDouble(-1239459382)
+ *           .setPInt32(-858673665)
+ *           .setPInt64(-858673570)
+ *           .setPDouble(-991225216)
+ *           .build();
+ *   RepeatResponse response = complianceClient.repeatDataBody(request);
+ * }
+ * }
        
+ *
+ * 
        ======================= EchoClient =======================
+ *
+ * 
        Service Description: This service is used showcase the four main types of rpcs - unary, server
+ * side streaming, client side streaming, and bidirectional streaming. This service also exposes
+ * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
+ * metadata key on any method to have the values echoed in the response trailers. Set the
+ * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
+ * headers.
+ *
+ * 
        Sample for EchoClient:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (EchoClient echoClient = EchoClient.create()) {
+ *   EchoRequest request =
+ *       EchoRequest.newBuilder()
+ *           .setSeverity(Severity.forNumber(0))
+ *           .setHeader("header-1221270899")
+ *           .setOtherHeader("otherHeader-2026585667")
+ *           .setRequestId("requestId693933066")
+ *           .setOtherRequestId("otherRequestId1248995034")
+ *           .build();
+ *   EchoResponse response = echoClient.echo(request);

+/**
+ * Settings class to configure an instance of {@link ComplianceStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of repeatDataBody:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceStubSettings.Builder complianceSettingsBuilder = ComplianceStubSettings.newBuilder();
+ * complianceSettingsBuilder
+ *     .repeatDataBodySettings()
+ *     .setRetrySettings(
+ *         complianceSettingsBuilder
+ *             .repeatDataBodySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * ComplianceStubSettings complianceSettings = complianceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link EchoStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of echo:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * EchoStubSettings echoSettings = echoSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for wait:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * echoSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Settings class to configure an instance of {@link IdentityStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createUser:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentityStubSettings.Builder identitySettingsBuilder = IdentityStubSettings.newBuilder();
+ * identitySettingsBuilder
+ *     .createUserSettings()
+ *     .setRetrySettings(
+ *         identitySettingsBuilder
+ *             .createUserSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * IdentityStubSettings identitySettings = identitySettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link MessagingStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createRoom:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingStubSettings.Builder messagingSettingsBuilder = MessagingStubSettings.newBuilder();
+ * messagingSettingsBuilder
+ *     .createRoomSettings()
+ *     .setRetrySettings(
+ *         messagingSettingsBuilder
+ *             .createRoomSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * MessagingStubSettings messagingSettings = messagingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for searchBlurbs:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingStubSettings.Builder messagingSettingsBuilder = MessagingStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * messagingSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link SequenceServiceStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSequence:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceStubSettings.Builder sequenceServiceSettingsBuilder =
+ *     SequenceServiceStubSettings.newBuilder();
+ * sequenceServiceSettingsBuilder
+ *     .createSequenceSettings()
+ *     .setRetrySettings(
+ *         sequenceServiceSettingsBuilder
+ *             .createSequenceSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * SequenceServiceStubSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link TestingStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSession:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingStubSettings.Builder testingSettingsBuilder = TestingStubSettings.newBuilder();
+ * testingSettingsBuilder
+ *     .createSessionSettings()
+ *     .setRetrySettings(
+ *         testingSettingsBuilder
+ *             .createSessionSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))

+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: This service is used to test that GAPICs implement various REST-related
+ * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
+ * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
+ * received by clients can be round-tripped correctly.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ComplianceClient complianceClient = ComplianceClient.create()) {
+ *   RepeatRequest request =
+ *       RepeatRequest.newBuilder()
+ *           .setName("name3373707")
+ *           .setInfo(ComplianceData.newBuilder().build())
+ *           .setServerVerify(true)
+ *           .setIntendedBindingUri("intendedBindingUri780142386")
+ *           .setFInt32(-1143775883)
+ *           .setFInt64(-1143775788)
+ *           .setFDouble(-1239459382)
+ *           .setPInt32(-858673665)
+ *           .setPInt64(-858673570)
+ *           .setPDouble(-991225216)
+ *           .build();
+ *   RepeatResponse response = complianceClient.repeatDataBody(request);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the ComplianceClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

        Methods
        MethodDescriptionMethod Variants
         RepeatDataBody
         This method echoes the ComplianceData request. This method exercises sending the entire request object in the REST body.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  repeatDataBody(RepeatRequest request)
+ *      
        
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  repeatDataBodyCallable()
+ *

         GetEnum
         This method requests an enum value from the server. Depending on the contents of EnumRequest, the enum value returned will be a known enum declared in the .proto file, or a made-up enum value the is unknown to the client. To verify that clients can round-trip unknown enum values they receive, use the response from this RPC as the request to VerifyEnum()
+ * 
          The values of enums sent by the server when a known or unknown value is requested will be the same within a single Showcase server run (this is needed for VerifyEnum() to work) but are not guaranteed to be the same across separate Showcase server runs.

         VerifyEnum
         This method is used to verify that clients can round-trip enum values, which is particularly important for unknown enum values over REST. VerifyEnum() verifies that its request, which is presumably the response that the client previously got to a GetEnum(), contains the correct data. If so, it responds with the same EnumResponse; otherwise, the RPC errors.
+ * 
          This works because the values of enums sent by the server when a known or unknown value is requested will be the same within a single Showcase server run, although they are not guaranteed to be the same across separate Showcase server runs.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of ComplianceSettings to
+ * create(). For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings =
+ *     ComplianceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings =
+ *     ComplianceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings = ComplianceSettings.newHttpJsonBuilder().build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link ComplianceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of repeatDataBody:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings.Builder complianceSettingsBuilder = ComplianceSettings.newBuilder();
+ * complianceSettingsBuilder
+ *     .repeatDataBodySettings()
+ *     .setRetrySettings(
+ *         complianceSettingsBuilder
+ *             .repeatDataBodySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+/**
+ * Service Description: This service is used showcase the four main types of rpcs - unary, server
+ * side streaming, client side streaming, and bidirectional streaming. This service also exposes
+ * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
+ * metadata key on any method to have the values echoed in the response trailers. Set the
+ * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
+ * headers.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.

+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (EchoClient echoClient = EchoClient.create()) {

        Methods
        MethodDescriptionMethod Variants
         Echo
         This method simply echoes the request. This method showcases unary RPCs.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  echo(EchoRequest request)
+ *      
        
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

        •  echoCallable()
+ *      
        
+ *       
         EchoErrorDetails
         This method returns error details in a repeated "google.protobuf.Any" field. This method showcases handling errors thus encoded, particularly over REST transport. Note that GAPICs only allow the type "google.protobuf.Any" for field paths ending in "error.details", and, at run-time, the actual types for these fields must be one of the types in google/rpc/error_details.proto.

        •  echoErrorDetailsCallable()
+ *      
        
+ *       
         FailEchoWithDetails
         This method always fails with a gRPC "Aborted" error status that contains multiple error details.  These include one instance of each of the standard ones in error_details.proto (https://github.com/googleapis/googleapis/blob/master/google/rpc/error_details.proto) plus a custom, Showcase-defined PoetryError. The intent of this RPC is to verify that GAPICs can process these various error details and surface them to the user in an idiomatic form.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *      
        
+ *       
         Collect

        •  chatCallable()
+ *      
        
+ *       
         PagedExpand
         This is similar to the Expand method but instead of returning a stream of expanded words, this method returns a paged list of expanded words.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *       
         PagedExpandLegacy
         This is similar to the PagedExpand except that it uses max_results instead of page_size, as some legacy APIs still do. New APIs should NOT use this pattern.

+ *      
        
+ *       
         PagedExpandLegacyMapped
         This method returns a map containing lists of words that appear in the input, keyed by their initial character. The only words returned are the ones included in the current page, as determined by page_token and page_size, which both refer to the word indices in the input. This paging result consisting of a map of lists is a pattern used by some legacy APIs. New APIs should NOT use this pattern.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of EchoSettings to create(). For
+ * example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings =
+ *     EchoSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings = EchoSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings = EchoSettings.newHttpJsonBuilder().build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link EchoClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of echo:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * EchoSettings echoSettings = echoSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for wait:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * echoSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Service Description: A simple identity service.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (IdentityClient identityClient = IdentityClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String email = "email96619420";
+ *   User response = identityClient.createUser(displayName, email);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the IdentityClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link IdentityClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createUser:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings.Builder identitySettingsBuilder = IdentitySettings.newBuilder();
+ * identitySettingsBuilder
+ *     .createUserSettings()
+ *     .setRetrySettings(
+ *         identitySettingsBuilder
+ *             .createUserSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * IdentitySettings identitySettings = identitySettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+ * Service Description: A simple messaging service that implements chat rooms and profile posts.
+ *
+ * 
        This messaging service showcases the features that API clients generated by gapic-generators
+ * implement.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (MessagingClient messagingClient = MessagingClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String description = "description-1724546052";
+ *   Room response = messagingClient.createRoom(displayName, description);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the MessagingClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with

+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of MessagingSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings =
+ *     MessagingSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings =
+ *     MessagingSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link MessagingClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createRoom:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings.Builder messagingSettingsBuilder = MessagingSettings.newBuilder();
+ * messagingSettingsBuilder
+ *     .createRoomSettings()
+ *     .setRetrySettings(
+ *         messagingSettingsBuilder
+ *             .createRoomSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * MessagingSettings messagingSettings = messagingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for searchBlurbs:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings.Builder messagingSettingsBuilder = MessagingSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * messagingSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link SequenceServiceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSequence:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library

+ *         sequenceServiceSettingsBuilder
+ *             .createSequenceSettings()

+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+ * SequenceServiceSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of TestingSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings =
+ *     TestingSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings = TestingSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings = TestingSettings.newHttpJsonBuilder().build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link TestingClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSession:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings.Builder testingSettingsBuilder = TestingSettings.newBuilder();
+ * testingSettingsBuilder
+ *     .createSessionSettings()
+ *     .setRetrySettings(
+ *         testingSettingsBuilder
+ *             .createSessionSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * TestingSettings testingSettings = testingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+/**
+ * Settings class to configure an instance of {@link ComplianceStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of repeatDataBody:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceStubSettings.Builder complianceSettingsBuilder = ComplianceStubSettings.newBuilder();
+ * complianceSettingsBuilder
+ *     .repeatDataBodySettings()
+ *     .setRetrySettings(
+ *         complianceSettingsBuilder
+ *             .repeatDataBodySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * ComplianceStubSettings complianceSettings = complianceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link EchoStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of echo:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * EchoStubSettings echoSettings = echoSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for wait:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * echoSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Settings class to configure an instance of {@link IdentityStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createUser:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentityStubSettings.Builder identitySettingsBuilder = IdentityStubSettings.newBuilder();
+ * identitySettingsBuilder
+ *     .createUserSettings()
+ *     .setRetrySettings(
+ *         identitySettingsBuilder
+ *             .createUserSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * IdentityStubSettings identitySettings = identitySettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+ * Settings class to configure an instance of {@link MessagingStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *

        For example, to set the

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link SequenceServiceStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSequence:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceStubSettings.Builder sequenceServiceSettingsBuilder =
+ *     SequenceServiceStubSettings.newBuilder();
+ * sequenceServiceSettingsBuilder
+ *     .createSequenceSettings()
+ *     .setRetrySettings(
+ *         sequenceServiceSettingsBuilder
+ *             .createSequenceSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * SequenceServiceStubSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link TestingStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSession:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingStubSettings.Builder testingSettingsBuilder = TestingStubSettings.newBuilder();
+ * testingSettingsBuilder
+ *     .createSessionSettings()
+ *     .setRetrySettings(
+ *         testingSettingsBuilder
+ *             .createSessionSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * TestingStubSettings testingSettings = testingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://github.com/googleapis/google-cloud-java/blob/main/docs/client_retries.md) for
+ * additional support in setting retries.

+[GAPIC Showcase](https://github.com/googleapis/gapic-showcase) is an API that demonstrates Generated
+API Client (GAPIC) features and common API patterns used by Google. It follows the [Cloud APIs
+design guide](https://cloud.google.com/apis/design/). `gapic-generator-java` generates a client for
+the Showcase API which can communicate with a local Showcase server to perform integration tests.
+
+## Requirements
+
+* Install [Go](https://go.dev) in your `PATH`.
+
+## Installing the Server
+
+Using the latest version of showcase is recommended, but backward compatibility between server
+versions is not guaranteed. If changing the version of the server, it may also be necessary to
+update to a compatible client version in `./WORKSPACE`.
+
+```shell
+# Install the showcase server version defined in gapic-showcase/pom.xml
+cd java-showcase
+go install github.com/googleapis/gapic-showcase/cmd/gapic-showcase@v"$(cd gapic-showcase;mvn help:evaluate -Dexpression=gapic-showcase.version -q -DforceStdout |sed 's/\x1b\[[0-9;]*m//g')"
+PATH=$PATH:`go env GOPATH`/bin
+gapic-showcase --help
+> Root command of gapic-showcase
+> 
+> Usage:
+>   gapic-showcase [command]
+> 
+> Available Commands:
+>   completion  Emits bash a completion for gapic-showcase
+>   compliance  This service is used to test that GAPICs...
+>   echo        This service is used showcase the four main types...
+>   help        Help about any command

+> 
+> Flags:
+>   -h, --help      help for gapic-showcase
+>   -j, --json      Print JSON output
+>   -v, --verbose   Print verbose output
+>       --version   version for gapic-showcase
+```
+
+## Running the Server
+
+Run the showcase server to allow requests to be sent to it. This opens port `:7469` to send and
+receive requests.
+
+```shell
+gapic-showcase run
+> 2022/11/21 16:22:15 Showcase listening on port: :7469
+> 2022/11/21 16:22:15 Starting endpoint 0: gRPC endpoint
+> 2022/11/21 16:22:15 Starting endpoint 1: HTTP/REST endpoint
+> 2022/11/21 16:22:15 Starting endpoint multiplexer
+> 2022/11/21 16:22:15 Listening for gRPC-fallback connections
+> 2022/11/21 16:22:15 Listening for gRPC connections
+> 2022/11/21 16:22:15 Listening for REST connections
+> 2022/11/21 16:22:15 Fallback server listening on port: :1337
+```
+
+## Running the Integration Tests
+
+Open a new terminal window in the root project directory.
+This step does not require Docker.
+
+```shell
+cd java-showcase
+mvn verify -P enable-integration-tests
+```
+
+## Running the Golden tests
+
+**NOTE** This requires Docker to be installed in your machine.
+Open a new terminal window in the root project directory.
+
+```shell
+cd java-showcase
+mvn verify -P enable-golden-tests
+```
+
+
+## Update the Golden Showcase Files
+
+**NOTE** This requires Docker to be installed in your machine.
+Open a new terminal window in the root project directory.
+
+```shell
+# In repository's root directory
+mvn clean install -DskipTests
+cd java-showcase
+mvn compile -P update
+```

+ * Service Description: This service is used to test that GAPICs implement various REST-related
+ * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
+ * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
+ * received by clients can be round-tripped correctly.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ComplianceClient complianceClient = ComplianceClient.create()) {
+ *   RepeatRequest request =
+ *       RepeatRequest.newBuilder()
+ *           .setName("name3373707")
+ *           .setInfo(ComplianceData.newBuilder().build())
+ *           .setServerVerify(true)
+ *           .setIntendedBindingUri("intendedBindingUri780142386")

+ * }
+ * }

        Note: close() needs to be called on the ComplianceClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

+ *       
         GetEnum
         This method requests an enum value from the server. Depending on the contents of EnumRequest, the enum value returned will be a known enum declared in the .proto file, or a made-up enum value the is unknown to the client. To verify that clients can round-trip unknown enum values they receive, use the response from this RPC as the request to VerifyEnum()
+ * 
          The values of enums sent by the server when a known or unknown value is requested will be the same within a single Showcase server run (this is needed for VerifyEnum() to work) but are not guaranteed to be the same across separate Showcase server runs.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

+ *           
        •  getEnum(EnumRequest request)

+ *           
        •  getEnumCallable()
+ *      
        
+ *       
         VerifyEnum
         This method is used to verify that clients can round-trip enum values, which is particularly important for unknown enum values over REST. VerifyEnum() verifies that its request, which is presumably the response that the client previously got to a GetEnum(), contains the correct data. If so, it responds with the same EnumResponse; otherwise, the RPC errors.
+ * 
          This works because the values of enums sent by the server when a known or unknown value is requested will be the same within a single Showcase server run, although they are not guaranteed to be the same across separate Showcase server runs.

        Request object method variants only take one parameter, a request object, which must be constructed before the call.

        See the individual methods for example code.
+ *
+ * 
        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of ComplianceSettings to
+ * create(). For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings =
+ *     ComplianceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings =
+ *     ComplianceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings complianceSettings = ComplianceSettings.newHttpJsonBuilder().build();
+ * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link ComplianceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of repeatDataBody:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceSettings.Builder complianceSettingsBuilder = ComplianceSettings.newBuilder();
+ * complianceSettingsBuilder
+ *     .repeatDataBodySettings()
+ *     .setRetrySettings(
+ *         complianceSettingsBuilder
+ *             .repeatDataBodySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * ComplianceSettings complianceSettings = complianceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: This service is used showcase the four main types of rpcs - unary, server
+ * side streaming, client side streaming, and bidirectional streaming. This service also exposes
+ * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
+ * metadata key on any method to have the values echoed in the response trailers. Set the
+ * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
+ * headers.
+ *
+ * 
        This client uses Echo version v1_20240408.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (EchoClient echoClient = EchoClient.create()) {
+ *   EchoRequest request =
+ *       EchoRequest.newBuilder()
+ *           .setSeverity(Severity.forNumber(0))
+ *           .setHeader("header-1221270899")
+ *           .setOtherHeader("otherHeader-2026585667")
+ *           .setRequestId("requestId693933066")
+ *           .setOtherRequestId("otherRequestId1248995034")
+ *           .build();
+ *   EchoResponse response = echoClient.echo(request);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the EchoClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

        Methods
        MethodDescriptionMethod Variants
         Echo
         This method simply echoes the request. This method showcases unary RPCs.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  echo(EchoRequest request)
+ *      
        
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  echoCallable()
+ *      
        
+ *       
         EchoErrorDetails
         This method returns error details in a repeated "google.protobuf.Any" field. This method showcases handling errors thus encoded, particularly over REST transport. Note that GAPICs only allow the type "google.protobuf.Any" for field paths ending in "error.details", and, at run-time, the actual types for these fields must be one of the types in google/rpc/error_details.proto.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  echoErrorDetails(EchoErrorDetailsRequest request)
+ *      
        
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  echoErrorDetailsCallable()
+ *      
        
+ *       
         FailEchoWithDetails
         This method always fails with a gRPC "Aborted" error status that contains multiple error details.  These include one instance of each of the standard ones in error_details.proto (https://github.com/googleapis/googleapis/blob/master/google/rpc/error_details.proto) plus a custom, Showcase-defined PoetryError. The intent of this RPC is to verify that GAPICs can process these various error details and surface them to the user in an idiomatic form.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *

+ *       
         Expand
         This method splits the given content into words and will pass each word back through the stream. This method showcases server-side streaming RPCs.
        		
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *           
        •  expandCallable()
+ *      
        
+ *       
         Collect
         This method will collect the words given to it. When the stream is closed by the client, this method will return the a concatenation of the strings passed to it. This method showcases client-side streaming RPCs.
        		
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

+ *           
        •  collectCallable()
+ *      
        
+ *       
         Chat
         This method, upon receiving a request on the stream, will pass the same content back on the stream. This method showcases bidirectional streaming RPCs.
        		
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  chatCallable()
+ *      
        
+ *       
         PagedExpand
         This is similar to the Expand method but instead of returning a stream of expanded words, this method returns a paged list of expanded words.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

        •  pagedExpandCallable()
+ *      
        
+ *       
         PagedExpandLegacy
         This is similar to the PagedExpand except that it uses max_results instead of page_size, as some legacy APIs still do. New APIs should NOT use this pattern.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

        •  pagedExpandLegacyCallable()
+ *      
        
+ *       
         PagedExpandLegacyMapped
         This method returns a map containing lists of words that appear in the input, keyed by their initial character. The only words returned are the ones included in the current page, as determined by page_token and page_size, which both refer to the word indices in the input. This paging result consisting of a map of lists is a pattern used by some legacy APIs. New APIs should NOT use this pattern.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

         TestIamPermissions
         Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a `NOT_FOUND` error.
+ * 
          Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of EchoSettings to create(). For
+ * example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings =
+ *     EchoSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings = EchoSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings echoSettings = EchoSettings.newHttpJsonBuilder().build();
+ * EchoClient echoClient = EchoClient.create(echoSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link EchoClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of echo:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * EchoSettings echoSettings = echoSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for wait:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * echoSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+ * Service Description: A simple identity service.

        This class provides the ability to make remote calls to the backing service through method

+ * // It will require modifications to work:

+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (IdentityClient identityClient = IdentityClient.create()) {

        See the individual methods for example code.

+ * 
        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of IdentitySettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings identitySettings =
+ *     IdentitySettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * IdentityClient identityClient = IdentityClient.create(identitySettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings identitySettings =
+ *     IdentitySettings.newBuilder().setEndpoint(myEndpoint).build();
+ * IdentityClient identityClient = IdentityClient.create(identitySettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings identitySettings = IdentitySettings.newHttpJsonBuilder().build();
+ * IdentityClient identityClient = IdentityClient.create(identitySettings);
+ * }

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link IdentityClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createUser:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentitySettings.Builder identitySettingsBuilder = IdentitySettings.newBuilder();
+ * identitySettingsBuilder
+ *     .createUserSettings()
+ *     .setRetrySettings(
+ *         identitySettingsBuilder
+ *             .createUserSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * IdentitySettings identitySettings = identitySettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+ * Service Description: A simple messaging service that implements chat rooms and profile posts.
+ *
+ * 
        This messaging service showcases the features that API clients generated by gapic-generators
+ * implement.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (MessagingClient messagingClient = MessagingClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String description = "description-1724546052";
+ *   Room response = messagingClient.createRoom(displayName, description);
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the MessagingClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().

         Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a `NOT_FOUND` error.

          Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

        See the individual methods for example code.

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of MessagingSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings =
+ *     MessagingSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings =
+ *     MessagingSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings messagingSettings = MessagingSettings.newHttpJsonBuilder().build();
+ * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link MessagingClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createRoom:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingSettings.Builder messagingSettingsBuilder = MessagingSettings.newBuilder();
+ * messagingSettingsBuilder
+ *     .createRoomSettings()
+ *     .setRetrySettings(
+ *         messagingSettingsBuilder
+ *             .createRoomSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)

        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of SequenceServiceSettings to
+ * create(). For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings sequenceServiceSettings =
+ *     SequenceServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * SequenceServiceClient sequenceServiceClient =
+ *     SequenceServiceClient.create(sequenceServiceSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings sequenceServiceSettings =
+ *     SequenceServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * SequenceServiceClient sequenceServiceClient =
+ *     SequenceServiceClient.create(sequenceServiceSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in

+/**
+ * Settings class to configure an instance of {@link SequenceServiceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSequence:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * SequenceServiceSettings.Builder sequenceServiceSettingsBuilder =
+ *     SequenceServiceSettings.newBuilder();
+ * sequenceServiceSettingsBuilder
+ *     .createSequenceSettings()
+ *     .setRetrySettings(
+ *         sequenceServiceSettingsBuilder
+ *             .createSequenceSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * SequenceServiceSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

        See the individual methods for example code.
+ *
+ * 
        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of TestingSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings =
+ *     TestingSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings = TestingSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings testingSettings = TestingSettings.newHttpJsonBuilder().build();
+ * TestingClient testingClient = TestingClient.create(testingSettings);
+ * }

+/**
+ * Settings class to configure an instance of {@link TestingClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSession:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingSettings.Builder testingSettingsBuilder = TestingSettings.newBuilder();
+ * testingSettingsBuilder
+ *     .createSessionSettings()
+ *     .setRetrySettings(
+ *         testingSettingsBuilder
+ *             .createSessionSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * TestingSettings testingSettings = testingSettingsBuilder.build();

+/**
+ * A client to Client Libraries Showcase API
+ *
+ * 
        The interfaces provided are listed below, along with usage samples.
+ *
+ * 
        ======================= ComplianceClient =======================
+ *
+ * 
        Service Description: This service is used to test that GAPICs implement various REST-related
+ * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
+ * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
+ * received by clients can be round-tripped correctly.
+ *
+ * 
        Sample for ComplianceClient:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ComplianceClient complianceClient = ComplianceClient.create()) {
+ *   RepeatRequest request =
+ *       RepeatRequest.newBuilder()
+ *           .setName("name3373707")
+ *           .setInfo(ComplianceData.newBuilder().build())
+ *           .setServerVerify(true)
+ *           .setIntendedBindingUri("intendedBindingUri780142386")
+ *           .setFInt32(-1143775883)
+ *           .setFInt64(-1143775788)
+ *           .setFDouble(-1239459382)
+ *           .setPInt32(-858673665)
+ *           .setPInt64(-858673570)
+ *           .setPDouble(-991225216)
+ *           .build();
+ *   RepeatResponse response = complianceClient.repeatDataBody(request);
+ * }
+ * }
        
+ *
+ * 
        ======================= EchoClient =======================
+ *
+ * 
        Service Description: This service is used showcase the four main types of rpcs - unary, server
+ * side streaming, client side streaming, and bidirectional streaming. This service also exposes
+ * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
+ * metadata key on any method to have the values echoed in the response trailers. Set the
+ * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
+ * headers.
+ *
+ * 
        Sample for EchoClient:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (EchoClient echoClient = EchoClient.create()) {
+ *   EchoRequest request =
+ *       EchoRequest.newBuilder()
+ *           .setSeverity(Severity.forNumber(0))
+ *           .setHeader("header-1221270899")
+ *           .setOtherHeader("otherHeader-2026585667")
+ *           .setRequestId("requestId693933066")
+ *           .setOtherRequestId("otherRequestId1248995034")
+ *           .build();
+ *   EchoResponse response = echoClient.echo(request);
+ * }
+ * }
        
+ *
+ * 
        ======================= IdentityClient =======================
+ *
+ * 
        Service Description: A simple identity service.
+ *
+ * 
        Sample for IdentityClient:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (IdentityClient identityClient = IdentityClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String email = "email96619420";
+ *   User response = identityClient.createUser(displayName, email);
+ * }
+ * }
        
+ *

+ * implement.
+ *
+ * 
        Sample for MessagingClient:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.

+ * try (MessagingClient messagingClient = MessagingClient.create()) {
+ *   String displayName = "displayName1714148973";
+ *   String description = "description-1724546052";
+ *   Room response = messagingClient.createRoom(displayName, description);
+ * }
+ * }
        
+ *
+ * 
        ======================= SequenceServiceClient =======================
+ *
+ * 
        Sample for SequenceServiceClient:

+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (SequenceServiceClient sequenceServiceClient = SequenceServiceClient.create()) {
+ *   Sequence sequence = Sequence.newBuilder().build();
+ *   Sequence response = sequenceServiceClient.createSequence(sequence);
+ * }
+ * }
        
+ *
+ * 
        ======================= TestingClient =======================
+ *
+ * 
        Service Description: A service to facilitate running discrete sets of tests against Showcase.
+ * Adding this comment with special characters for comment formatting tests: 1.
+ * (abra->kadabra->alakazam) 2) [Nonsense][]: `pokemon/*/psychic/*`
+ *
+ * 
        Sample for TestingClient:
+ *
+ * 
        {@code

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link ComplianceStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of repeatDataBody:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ComplianceStubSettings.Builder complianceSettingsBuilder = ComplianceStubSettings.newBuilder();
+ * complianceSettingsBuilder
+ *     .repeatDataBodySettings()
+ *     .setRetrySettings(
+ *         complianceSettingsBuilder
+ *             .repeatDataBodySettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * ComplianceStubSettings complianceSettings = complianceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+/**
+ * Settings class to configure an instance of {@link EchoStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of echo:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * echoSettingsBuilder
+ *     .echoSettings()
+ *     .setRetrySettings(
+ *         echoSettingsBuilder
+ *             .echoSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * EchoStubSettings echoSettings = echoSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for wait:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * echoSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Settings class to configure an instance of {@link IdentityStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createUser:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * IdentityStubSettings.Builder identitySettingsBuilder = IdentityStubSettings.newBuilder();
+ * identitySettingsBuilder
+ *     .createUserSettings()
+ *     .setRetrySettings(
+ *         identitySettingsBuilder
+ *             .createUserSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link MessagingStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createRoom:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingStubSettings.Builder messagingSettingsBuilder = MessagingStubSettings.newBuilder();
+ * messagingSettingsBuilder
+ *     .createRoomSettings()
+ *     .setRetrySettings(
+ *         messagingSettingsBuilder
+ *             .createRoomSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * MessagingStubSettings messagingSettings = messagingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.
+ *
+ * 
        To configure the RetrySettings of a Long Running Operation method, create an
+ * OperationTimedPollAlgorithm object and update the RPC's polling algorithm. For example, to
+ * configure the RetrySettings for searchBlurbs:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * MessagingStubSettings.Builder messagingSettingsBuilder = MessagingStubSettings.newBuilder();
+ * TimedRetryAlgorithm timedRetryAlgorithm =
+ *     OperationalTimedPollAlgorithm.create(
+ *         RetrySettings.newBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofMillis(500))
+ *             .setRetryDelayMultiplier(1.5)
+ *             .setMaxRetryDelayDuration(Duration.ofMillis(5000))
+ *             .setTotalTimeoutDuration(Duration.ofHours(24))
+ *             .build());
+ * messagingSettingsBuilder
+ *     .createClusterOperationSettings()
+ *     .setPollingAlgorithm(timedRetryAlgorithm)
+ *     .build();
+ * }

+/**
+ * Settings class to configure an instance of {@link SequenceServiceStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSequence:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link TestingStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (localhost) and default port (7469) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of createSession:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TestingStubSettings.Builder testingSettingsBuilder = TestingStubSettings.newBuilder();
+ * testingSettingsBuilder
+ *     .createSessionSettings()
+ *     .setRetrySettings(
+ *         testingSettingsBuilder
+ *             .createSessionSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * TestingStubSettings testingSettings = testingSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+# - Modifies the gapic-generator-bom version in java-shared-dependencies.
+# - Updates the version of native-maven-plugin in java-shared-config.

-/**
- * Service Description: This service is used to test that GAPICs implement various REST-related
- * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
- * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
- * received by clients can be round-tripped correctly.
- *
- * 
        This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (ComplianceClient complianceClient = ComplianceClient.create()) {
- *   RepeatRequest request =
- *       RepeatRequest.newBuilder()
- *           .setName("name3373707")
- *           .setInfo(ComplianceData.newBuilder().build())
- *           .setServerVerify(true)
- *           .setIntendedBindingUri("intendedBindingUri780142386")
- *           .setFInt32(-1143775883)
- *           .setFInt64(-1143775788)
- *           .setFDouble(-1239459382)
- *           .setPInt32(-858673665)
- *           .setPInt64(-858673570)
- *           .setPDouble(-991225216)
- *           .build();
- *   RepeatResponse response = complianceClient.repeatDataBody(request);
- * }
- * }
        
- *
- * 
        Note: close() needs to be called on the ComplianceClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of ComplianceSettings to
- * create(). For example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * ComplianceSettings complianceSettings =
- *     ComplianceSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * ComplianceSettings complianceSettings =
- *     ComplianceSettings.newBuilder().setEndpoint(myEndpoint).build();
- * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * ComplianceSettings complianceSettings = ComplianceSettings.newHttpJsonBuilder().build();
- * ComplianceClient complianceClient = ComplianceClient.create(complianceSettings);
- * }

-/**
- * Settings class to configure an instance of {@link ComplianceClient}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of repeatDataBody to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * ComplianceSettings.Builder complianceSettingsBuilder = ComplianceSettings.newBuilder();
- * complianceSettingsBuilder
- *     .repeatDataBodySettings()
- *     .setRetrySettings(
- *         complianceSettingsBuilder
- *             .repeatDataBodySettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * ComplianceSettings complianceSettings = complianceSettingsBuilder.build();
- * }

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: This service is used showcase the four main types of rpcs - unary, server
- * side streaming, client side streaming, and bidirectional streaming. This service also exposes
- * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
- * metadata key on any method to have the values echoed in the response trailers. Set the
- * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
- * headers.
- *
- * 
        This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (EchoClient echoClient = EchoClient.create()) {
- *   EchoRequest request =
- *       EchoRequest.newBuilder()
- *           .setSeverity(Severity.forNumber(0))
- *           .setHeader("header-1221270899")
- *           .setOtherHeader("otherHeader-2026585667")
- *           .build();
- *   EchoResponse response = echoClient.echo(request);
- * }
- * }
        
- *
- * 
        Note: close() needs to be called on the EchoClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of EchoSettings to create(). For
- * example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoSettings echoSettings =
- *     EchoSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * EchoClient echoClient = EchoClient.create(echoSettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoSettings echoSettings = EchoSettings.newBuilder().setEndpoint(myEndpoint).build();
- * EchoClient echoClient = EchoClient.create(echoSettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoSettings echoSettings = EchoSettings.newHttpJsonBuilder().build();
- * EchoClient echoClient = EchoClient.create(echoSettings);
- * }
        
- *
- * 
        Please refer to the GitHub repository's samples for more quickstart code snippets.

-/**
- * Settings class to configure an instance of {@link EchoClient}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of echo to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoSettings.Builder echoSettingsBuilder = EchoSettings.newBuilder();
- * echoSettingsBuilder
- *     .echoSettings()
- *     .setRetrySettings(
- *         echoSettingsBuilder
- *             .echoSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * EchoSettings echoSettings = echoSettingsBuilder.build();
- * }

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: A simple identity service.
- *
- * 
        This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (IdentityClient identityClient = IdentityClient.create()) {
- *   String displayName = "displayName1714148973";
- *   String email = "email96619420";
- *   User response = identityClient.createUser(displayName, email);
- * }
- * }
        
- *
- * 
        Note: close() needs to be called on the IdentityClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of IdentitySettings to create().
- * For example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * IdentitySettings identitySettings =
- *     IdentitySettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * IdentityClient identityClient = IdentityClient.create(identitySettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * IdentitySettings identitySettings =
- *     IdentitySettings.newBuilder().setEndpoint(myEndpoint).build();
- * IdentityClient identityClient = IdentityClient.create(identitySettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * IdentitySettings identitySettings = IdentitySettings.newHttpJsonBuilder().build();
- * IdentityClient identityClient = IdentityClient.create(identitySettings);
- * }
        
- *
- * 
        Please refer to the GitHub repository's samples for more quickstart code snippets.

-/**
- * Settings class to configure an instance of {@link IdentityClient}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createUser to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * IdentitySettings.Builder identitySettingsBuilder = IdentitySettings.newBuilder();
- * identitySettingsBuilder
- *     .createUserSettings()
- *     .setRetrySettings(
- *         identitySettingsBuilder
- *             .createUserSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * IdentitySettings identitySettings = identitySettingsBuilder.build();
- * }

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: A simple messaging service that implements chat rooms and profile posts.
- *
- * 
        This messaging service showcases the features that API clients generated by gapic-generators
- * implement.
- *
- * 
        This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (MessagingClient messagingClient = MessagingClient.create()) {
- *   String displayName = "displayName1714148973";
- *   String description = "description-1724546052";
- *   Room response = messagingClient.createRoom(displayName, description);
- * }
- * }
        
- *
- * 
        Note: close() needs to be called on the MessagingClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of MessagingSettings to create().
- * For example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * MessagingSettings messagingSettings =
- *     MessagingSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * MessagingSettings messagingSettings =
- *     MessagingSettings.newBuilder().setEndpoint(myEndpoint).build();
- * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * MessagingSettings messagingSettings = MessagingSettings.newHttpJsonBuilder().build();
- * MessagingClient messagingClient = MessagingClient.create(messagingSettings);
- * }
        
- *
- * 
        Please refer to the GitHub repository's samples for more quickstart code snippets.

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link MessagingClient}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createRoom to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * MessagingSettings.Builder messagingSettingsBuilder = MessagingSettings.newBuilder();
- * messagingSettingsBuilder
- *     .createRoomSettings()
- *     .setRetrySettings(
- *         messagingSettingsBuilder
- *             .createRoomSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * MessagingSettings messagingSettings = messagingSettingsBuilder.build();
- * }

- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of SequenceServiceSettings to
- * create(). For example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * SequenceServiceSettings sequenceServiceSettings =
- *     SequenceServiceSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * SequenceServiceClient sequenceServiceClient =
- *     SequenceServiceClient.create(sequenceServiceSettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * SequenceServiceSettings sequenceServiceSettings =
- *     SequenceServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
- * SequenceServiceClient sequenceServiceClient =
- *     SequenceServiceClient.create(sequenceServiceSettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * SequenceServiceSettings sequenceServiceSettings =
- *     SequenceServiceSettings.newHttpJsonBuilder().build();
- * SequenceServiceClient sequenceServiceClient =
- *     SequenceServiceClient.create(sequenceServiceSettings);
- * }

-/**
- * Settings class to configure an instance of {@link SequenceServiceClient}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createSequence to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * SequenceServiceSettings.Builder sequenceServiceSettingsBuilder =
- *     SequenceServiceSettings.newBuilder();
- * sequenceServiceSettingsBuilder
- *     .createSequenceSettings()
- *     .setRetrySettings(
- *         sequenceServiceSettingsBuilder
- *             .createSequenceSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * SequenceServiceSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();
- * }

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: A service to facilitate running discrete sets of tests against Showcase.
- *
- * 
        This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (TestingClient testingClient = TestingClient.create()) {
- *   CreateSessionRequest request =
- *       CreateSessionRequest.newBuilder().setSession(Session.newBuilder().build()).build();
- *   Session response = testingClient.createSession(request);
- * }
- * }
        
- *
- * 
        Note: close() needs to be called on the TestingClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * 
        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * 
        
- *
- * 
        See the individual methods for example code.
- *
- * 
        Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * 
        This class can be customized by passing in a custom instance of TestingSettings to create().
- * For example:
- *
- * 
        To customize credentials:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * TestingSettings testingSettings =
- *     TestingSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * TestingClient testingClient = TestingClient.create(testingSettings);
- * }
        
- *
- * 
        To customize the endpoint:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * TestingSettings testingSettings = TestingSettings.newBuilder().setEndpoint(myEndpoint).build();
- * TestingClient testingClient = TestingClient.create(testingSettings);
- * }
        
- *
- * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
- * the wire:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * TestingSettings testingSettings = TestingSettings.newHttpJsonBuilder().build();
- * TestingClient testingClient = TestingClient.create(testingSettings);
- * }
        
- *
- * 
        Please refer to the GitHub repository's samples for more quickstart code snippets.

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Settings class to configure an instance of {@link TestingClient}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createSession to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * TestingSettings.Builder testingSettingsBuilder = TestingSettings.newBuilder();
- * testingSettingsBuilder
- *     .createSessionSettings()
- *     .setRetrySettings(
- *         testingSettingsBuilder
- *             .createSessionSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * TestingSettings testingSettings = testingSettingsBuilder.build();
- * }

-/**
- * A client to Client Libraries Showcase API
- *
- * 
        The interfaces provided are listed below, along with usage samples.
- *
- * 
        ======================= ComplianceClient =======================
- *
- * 
        Service Description: This service is used to test that GAPICs implement various REST-related
- * features correctly. This mostly means transcoding proto3 requests to REST format correctly for
- * various types of HTTP annotations, but it also includes verifying that unknown (numeric) enums
- * received by clients can be round-tripped correctly.
- *
- * 
        Sample for ComplianceClient:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (ComplianceClient complianceClient = ComplianceClient.create()) {
- *   RepeatRequest request =
- *       RepeatRequest.newBuilder()
- *           .setName("name3373707")
- *           .setInfo(ComplianceData.newBuilder().build())
- *           .setServerVerify(true)
- *           .setIntendedBindingUri("intendedBindingUri780142386")
- *           .setFInt32(-1143775883)
- *           .setFInt64(-1143775788)
- *           .setFDouble(-1239459382)
- *           .setPInt32(-858673665)
- *           .setPInt64(-858673570)
- *           .setPDouble(-991225216)
- *           .build();
- *   RepeatResponse response = complianceClient.repeatDataBody(request);
- * }
- * }
        
- *
- * 
        ======================= EchoClient =======================
- *
- * 
        Service Description: This service is used showcase the four main types of rpcs - unary, server
- * side streaming, client side streaming, and bidirectional streaming. This service also exposes
- * methods that explicitly implement server delay, and paginated calls. Set the 'showcase-trailer'
- * metadata key on any method to have the values echoed in the response trailers. Set the
- * 'x-goog-request-params' metadata key on any method to have the values echoed in the response
- * headers.
- *
- * 
        Sample for EchoClient:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (EchoClient echoClient = EchoClient.create()) {
- *   EchoRequest request =
- *       EchoRequest.newBuilder()
- *           .setSeverity(Severity.forNumber(0))
- *           .setHeader("header-1221270899")
- *           .setOtherHeader("otherHeader-2026585667")
- *           .build();
- *   EchoResponse response = echoClient.echo(request);
- * }
- * }
        
- *
- * 
        ======================= IdentityClient =======================
- *
- * 
        Service Description: A simple identity service.
- *
- * 
        Sample for IdentityClient:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (IdentityClient identityClient = IdentityClient.create()) {
- *   String displayName = "displayName1714148973";
- *   String email = "email96619420";
- *   User response = identityClient.createUser(displayName, email);
- * }
- * }
        
- *
- * 
        ======================= MessagingClient =======================
- *
- * 
        Service Description: A simple messaging service that implements chat rooms and profile posts.
- *
- * 
        This messaging service showcases the features that API clients generated by gapic-generators
- * implement.
- *
- * 
        Sample for MessagingClient:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in

- * try (MessagingClient messagingClient = MessagingClient.create()) {
- *   String displayName = "displayName1714148973";
- *   String description = "description-1724546052";
- *   Room response = messagingClient.createRoom(displayName, description);
- * }
- * }
        
- *
- * 
        ======================= SequenceServiceClient =======================
- *
- * 
        Sample for SequenceServiceClient:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * try (SequenceServiceClient sequenceServiceClient = SequenceServiceClient.create()) {
- *   Sequence sequence = Sequence.newBuilder().build();

-/**
- * Settings class to configure an instance of {@link ComplianceStub}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of repeatDataBody to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * ComplianceStubSettings.Builder complianceSettingsBuilder = ComplianceStubSettings.newBuilder();
- * complianceSettingsBuilder
- *     .repeatDataBodySettings()
- *     .setRetrySettings(
- *         complianceSettingsBuilder
- *             .repeatDataBodySettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * ComplianceStubSettings complianceSettings = complianceSettingsBuilder.build();
- * }

-/**
- * Settings class to configure an instance of {@link EchoStub}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of echo to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * EchoStubSettings.Builder echoSettingsBuilder = EchoStubSettings.newBuilder();
- * echoSettingsBuilder
- *     .echoSettings()
- *     .setRetrySettings(
- *         echoSettingsBuilder
- *             .echoSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * EchoStubSettings echoSettings = echoSettingsBuilder.build();
- * }

-/**
- * Settings class to configure an instance of {@link IdentityStub}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createUser to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * IdentityStubSettings.Builder identitySettingsBuilder = IdentityStubSettings.newBuilder();
- * identitySettingsBuilder
- *     .createUserSettings()
- *     .setRetrySettings(
- *         identitySettingsBuilder
- *             .createUserSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * IdentityStubSettings identitySettings = identitySettingsBuilder.build();
- * }

-/**
- * Settings class to configure an instance of {@link MessagingStub}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createRoom to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * MessagingStubSettings.Builder messagingSettingsBuilder = MessagingStubSettings.newBuilder();

-/**
- * Settings class to configure an instance of {@link SequenceServiceStub}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createSequence to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * SequenceServiceStubSettings.Builder sequenceServiceSettingsBuilder =
- *     SequenceServiceStubSettings.newBuilder();
- * sequenceServiceSettingsBuilder
- *     .createSequenceSettings()
- *     .setRetrySettings(
- *         sequenceServiceSettingsBuilder
- *             .createSequenceSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * SequenceServiceStubSettings sequenceServiceSettings = sequenceServiceSettingsBuilder.build();

-/**
- * Settings class to configure an instance of {@link TestingStub}.
- *
- * 
        The default instance has everything set to sensible defaults:
- *
- * 
          
- *   
        • The default service address (localhost) and default port (7469) are used.
- *   
        • Credentials are acquired automatically through Application Default Credentials.
- *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
- * 
        
- *
- * 
        The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * 
        For example, to set the total timeout of createSession to 30 seconds:
- *
- * 
        {@code
- * // This snippet has been automatically generated and should be regarded as a code template only.
- * // It will require modifications to work:
- * // - It may require correct/in-range values for request initialization.
- * // - It may require specifying regional endpoints when creating the service client as shown in
- * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
- * TestingStubSettings.Builder testingSettingsBuilder = TestingStubSettings.newBuilder();
- * testingSettingsBuilder
- *     .createSessionSettings()
- *     .setRetrySettings(
- *         testingSettingsBuilder
- *             .createSessionSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * TestingStubSettings testingSettings = testingSettingsBuilder.build();
- * }

 # Goldens Files For Integration Test
 
 This folder contains goldens files that are expected to be generated from Java Microgenerator
-against different APIs. For example `redis` folder has all the Java source files in the generated 
+against different APIs. For example `redis` folder has all the Java source files in the generated
 Redis client library. They are all actual Java files, but used as goldens.
 
 ## Purpose
 
-When running integration test for the Java Microgenerator using the below command, 
-the goldens files in this folder will be used to compare with the actual generated Java source files.
+When running integration test for the Java Microgenerator using the below command,

+files.
 If they are not identical, then the integration test will fail.
 
 ```sh
-bazel test //test/integration:redis
+bazelisk test //test/integration:redis
 ```
 
 ## How To Update Goldens
 
 If the actual generated Java source files are not identical with the goldens files, and we want to
-update the goldens using source files. Run the command below to overwrite the goldens files in `redis` folder.
+update the goldens using source files. Run the command below to overwrite the goldens files

 ```sh
-bazel run //test/integration:update_redis
+# In repository's root directory
+mvn clean install -DskipTests
+bazelisk run //test/integration:update_redis
 ```
 
 ## Adding new integration tests
 
-If you are adding a new API for integration testing, be sure to add it in the `BUILD.bazel` under the `Integration Test Rules` and add the `java_gapic_test` rules for the new API under the `API Library Rules` section.

+the `Integration Test Rules` and add the `java_gapic_test` rules for the new API under
+the `API Library Rules` section.
 
-You need to manually create a new directory for your new API under the `test/integration/goldens` with the same name you've used for the `Integration Test Rules`. Then when you run the command to update goldens (above), it will automatically create the goldens needed.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: Service Interface for the Apigee Connect connection management APIs.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (ConnectionServiceClient connectionServiceClient = ConnectionServiceClient.create()) {
+ *   EndpointName parent = EndpointName.of("[PROJECT]", "[ENDPOINT]");
+ *   for (Connection element : connectionServiceClient.listConnections(parent).iterateAll()) {
+ *     // doThingsWith(element);
+ *   }
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the ConnectionServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * 
+ *    
+ *    
+ *      
+ *      
+ *      
+ *    
+ *    
+ *      
+ *      
+ *      
+ *

        Methods
        MethodDescriptionMethod Variants
         ListConnections
         Lists connections that are currently active for the given Apigee Connect endpoint.
        		
+ *      
        Request object method variants only take one parameter, a request object, which must be constructed before the call.
        
+ *      
          
+ *           
        •  listConnections(ListConnectionsRequest request)
+ *      
        
+ *      
        "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.
        
+ *      
          
+ *           
        •  listConnections(EndpointName parent)
+ *           
        •  listConnections(String parent)
+ *      
        
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  listConnectionsPagedCallable()
+ *           
        •  listConnectionsCallable()
+ *      
        
+ *       
        
+ *
+ * 
        See the individual methods for example code.
+ *
+ * 
        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of ConnectionServiceSettings to
+ * create(). For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConnectionServiceSettings connectionServiceSettings =
+ *     ConnectionServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * ConnectionServiceClient connectionServiceClient =
+ *     ConnectionServiceClient.create(connectionServiceSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConnectionServiceSettings connectionServiceSettings =
+ *     ConnectionServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * ConnectionServiceClient connectionServiceClient =
+ *     ConnectionServiceClient.create(connectionServiceSettings);
+ * }
        
+ *
+ * 
        To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over
+ * the wire:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConnectionServiceSettings connectionServiceSettings =
+ *     ConnectionServiceSettings.newHttpJsonBuilder().build();
+ * ConnectionServiceClient connectionServiceClient =
+ *     ConnectionServiceClient.create(connectionServiceSettings);
+ * }
        
+ *
+ * 
        Please refer to the GitHub repository's samples for more quickstart code snippets.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link ConnectionServiceClient}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (apigeeconnect.googleapis.com) and default port (443) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of listConnections:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * ConnectionServiceSettings.Builder connectionServiceSettingsBuilder =
+ *     ConnectionServiceSettings.newBuilder();
+ * connectionServiceSettingsBuilder
+ *     .listConnectionsSettings()
+ *     .setRetrySettings(
+ *         connectionServiceSettingsBuilder
+ *             .listConnectionsSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setInitialRetryDelayDuration(Duration.ofSeconds(1))
+ *             .setInitialRpcTimeoutDuration(Duration.ofSeconds(5))
+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)
+ *             .setRpcTimeoutMultiplier(1.5)
+ *             .setTotalTimeoutDuration(Duration.ofSeconds(300))
+ *             .build());
+ * ConnectionServiceSettings connectionServiceSettings = connectionServiceSettingsBuilder.build();
+ * }
        
+ *
+ * Please refer to the [Client Side Retry
+ * Guide](https://docs.cloud.google.com/java/docs/client-retries) for additional support in setting
+ * retries.

+/**
+ * Service Description: Tether provides a way for the control plane to send HTTP API requests to
+ * services in data planes that runs in a remote datacenter without requiring customers to open
+ * firewalls on their runtime plane.
+ *
+ * 
        This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * try (TetherClient tetherClient = TetherClient.create()) {
+ *   BidiStream bidiStream = tetherClient.egressCallable().call();
+ *   EgressResponse request =
+ *       EgressResponse.newBuilder()
+ *           .setId("id3355")
+ *           .setHttpResponse(HttpResponse.newBuilder().build())
+ *           .setStatus(Status.newBuilder().build())
+ *           .setProject("project-309310695")
+ *           .setTraceId("traceId-1067401920")
+ *           .setEndpoint(TetherEndpoint.forNumber(0))
+ *           .setName("name3373707")
+ *           .build();
+ *   bidiStream.send(request);
+ *   for (EgressRequest response : bidiStream) {
+ *     // Do something when a response is received.
+ *   }
+ * }
+ * }
        
+ *
+ * 
        Note: close() needs to be called on the TetherClient object to clean up resources such as
+ * threads. In the example above, try-with-resources is used, which automatically calls close().
+ *
+ * 
+ *    
+ *    
+ *

        Methods
        MethodDescriptionMethod Variants
         Egress
         Egress streams egress requests and responses. Logically, this is not actually a streaming request, but uses streaming as a mechanism to flip the client-server relationship of gRPC so that the server can act as a client. The listener, the RPC server, accepts connections from the dialer, the RPC client. The listener streams http requests and the dialer streams http responses.
        		
+ *      
        Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
        
+ *      
          
+ *           
        •  egressCallable()
+ *      
        
+ *       
        
+ *
+ * 
        See the individual methods for example code.
+ *
+ * 
        Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * 
        This class can be customized by passing in a custom instance of TetherSettings to create().
+ * For example:
+ *
+ * 
        To customize credentials:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TetherSettings tetherSettings =
+ *     TetherSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * TetherClient tetherClient = TetherClient.create(tetherSettings);
+ * }
        
+ *
+ * 
        To customize the endpoint:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TetherSettings tetherSettings = TetherSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * TetherClient tetherClient = TetherClient.create(tetherSettings);
+ * }
        
+ *
+ * 
        Please refer to the GitHub repository's samples for more quickstart code snippets.

+/**
+ * Settings class to configure an instance of {@link TetherStub}.
+ *
+ * 
        The default instance has everything set to sensible defaults:
+ *
+ * 
          
+ *   
        • The default service address (apigeeconnect.googleapis.com) and default port (443) are used.
+ *   
        • Credentials are acquired automatically through Application Default Credentials.
+ *   
        • Retries are configured for idempotent methods but not for non-idempotent methods.
+ * 
        
+ *
+ * 
        The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * 
        For example, to set the
+ * [RetrySettings](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings)
+ * of egress:
+ *
+ * 
        {@code
+ * // This snippet has been automatically generated and should be regarded as a code template only.
+ * // It will require modifications to work:
+ * // - It may require correct/in-range values for request initialization.
+ * // - It may require specifying regional endpoints when creating the service client as shown in
+ * // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
+ * TetherStubSettings.Builder tetherSettingsBuilder = TetherStubSettings.newBuilder();

+ *             .setMaxAttempts(5)
+ *             .setMaxRetryDelayDuration(Duration.ofSeconds(30))
+ *             .setMaxRpcTimeoutDuration(Duration.ofSeconds(60))
+ *             .setRetryDelayMultiplier(1.3)

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        Methods
        MethodDescriptionMethod Variants
         ExportAssets
         Exports assets with time and resource types to a given Cloud Storage location/BigQuery table. For Cloud Storage location destinations, the output format is newline-delimited JSON. Each line represents a [google.cloud.asset.v1.Asset][google.cloud.asset.v1.Asset] in the JSON format; for BigQuery table destinations, the output table stores the fields in asset Protobuf as columns. This API implements the [google.longrunning.Operation][google.longrunning.Operation] API, which allows you to keep track of the export. We recommend intervals of at least 2 seconds with exponential retry to poll the export operation result. For regular-size resource parent, the export operation usually finishes within 5 minutes.

        Request object method variants only take one parameter, a request object, which must be constructed before the call.

         BatchGetAssetsHistory
         Batch gets the update history of assets that overlap a time window. For IAM_POLICY content, this API outputs history when the asset and its attached IAM POLICY both exist. This can create gaps in the output history. Otherwise, this API outputs history with asset in both non-delete or deleted status. If a specified asset does not exist, this API returns an INVALID_ARGUMENT error.

This method implements the [google.longrunning.Operation][google.longrunning.Operation], which allows you to track the operation status. We recommend intervals of at least 2 seconds with exponential backoff retry to poll the operation result. The metadata contains the metadata for the long-running operation.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        MethodDescriptionMethod Variants
         ReadRows
         Streams back the contents of all requested rows in key order, optionally applying the same Reader filter to each. Depending on their size, rows and cells may be broken up across multiple responses, but atomicity of each row will still be preserved. See the ReadRowsResponse documentation for details.

         SampleRowKeys
         Returns a sample of row keys in the table. The returned row keys will delimit contiguous sections of the table of approximately equal size, which can be used to break up the data for distributed tasks like mapreduces.

  * threads. In the example above, try-with-resources is used, which automatically calls close().

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        1. A "flattened" method. With this type of method, the fields of the request type have been

- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

         Get
         Retrieves the specified region-specific Operations resource.

        Request object method variants only take one parameter, a request object, which must be constructed before the call.

        •  get(GetRegionOperationRequest request)
+ *      
        
+ *      
        "Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.
        
+ *      
          
+ *           
        •  get(String project, String region, String operation)

+ *      
        
+ *       
         Wait
         Waits for the specified Operation resource to return as `DONE` or for the request to approach the 2 minute deadline, and retrieves the specified Operation resource. This method differs from the `GET` method in that it waits for no more than the default deadline (2 minutes) and then returns the current state of the operation, which might be `DONE` or still in progress.
+ * 
          This method is called on a best-effort basis. Specifically: - In uncommon cases, when the server is overloaded, the request might return before the default deadline is reached, or might return after zero seconds. - If the default deadline is reached, there is no guarantee that the operation is actually done when the method returns. Be prepared to retry if the operation is not `DONE`.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        Note: close() needs to be called on the ConfigClient object to clean up resources such as
  * threads. In the example above, try-with-resources is used, which automatically calls close().

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

- * methods:

        1. A "flattened" method. With this type of method, the fields of the request type have been

- *       parameters, and not every API method will have a flattened method entry point.

- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        MethodDescriptionMethod Variants
         DeleteLog
         Deletes all the log entries in a log for the _Default Log Bucket. The log reappears if it receives new entries. Log entries written shortly before the delete operation might not be deleted. Entries received after the delete operation with a timestamp before the operation will be deleted.

         WriteLogEntries
         Writes log entries to Logging. This API method is the only way to send log entries to Logging. This method is used, directly or indirectly, by the Logging agent (fluentd) and all logging libraries configured to use Logging. A single request may contain log entries for a maximum of 1000 different resources (projects, organizations, billing accounts or folders)

- * methods:

- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

         CreateSubscription
         Creates a subscription to a given topic. See the [resource name rules] (https://cloud.google.com/pubsub/docs/admin#resource_names). If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`.
+ * 
          If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/admin#resource_names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

+ *       
         DeleteSubscription
         Deletes an existing subscription. All messages retained in the subscription are immediately dropped. Calls to `Pull` after deletion will return `NOT_FOUND`. After a subscription is deleted, a new one may be created with the same name, but the new one has no association with the old subscription or its topic unless the same topic is specified.

         ModifyAckDeadline
         Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level `ackDeadlineSeconds` used for subsequent messages.

         Acknowledge
         Acknowledges the messages associated with the `ack_ids` in the `AcknowledgeRequest`. The Pub/Sub system can remove the relevant messages from the subscription.
+ * 
          Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.

         StreamingPull
         Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgements and ack deadline modifications back to the server. The server will close the stream and return the status on any error. The server may close the stream with status `UNAVAILABLE` to reassign server-side resources, in which case, the client should re-establish the stream. Flow control can be achieved by configuring the underlying RPC channel.

         Creates a snapshot from the requested subscription. Snapshots are used in [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. If the snapshot already exists, returns `ALREADY_EXISTS`. If the requested subscription doesn't exist, returns `NOT_FOUND`. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned. See also the `Snapshot.expire_time` field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/admin#resource_names). The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:

- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been

- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

         DeleteTopic
         Deletes the topic with the given name. Returns `NOT_FOUND` if the topic does not exist. After a topic is deleted, a new topic may be created with the same name; this is an entirely new topic with none of the old configuration or subscriptions. Existing subscriptions to this topic are not deleted, but their `topic` field is set to `_deleted-topic_`.

          The creation is executed asynchronously and callers may check the returned operation to track its progress. Once the operation is completed the Redis instance will be fully functional. The completed longrunning.Operation will contain the new instance object in the response field.

        The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * 
          
- *   
        1. A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   
        2. A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   
        3. A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.

         WriteObject
         Stores a new object and metadata.
+ * 
          An object can be written either in a single message stream or in a resumable sequence of message streams. To write using a single stream, the client should include in the first message of the stream an `WriteObjectSpec` describing the destination bucket, object, and any preconditions. Additionally, the final message must set 'finish_write' to true, or else it is an error.
+ * 
          For a resumable write, the client should instead call `StartResumableWrite()`, populating a `WriteObjectSpec` into that request. They should then attach the returned `upload_id` to the first message of each following call to `WriteObject`. If the stream is closed before finishing the upload (either explicitly by the client or due to a network error or an error response from the server), the client should do as follows:   - Check the result Status of the stream, to determine if writing can be     resumed on this stream or must be restarted from scratch (by calling     `StartResumableWrite()`). The resumable errors are DEADLINE_EXCEEDED,     INTERNAL, and UNAVAILABLE. For each case, the client should use binary     exponential backoff before retrying.  Additionally, writes can be     resumed after RESOURCE_EXHAUSTED errors, but only after taking     appropriate measures, which may include reducing aggregate send rate     across clients and/or requesting a quota increase for your project.   - If the call to `WriteObject` returns `ABORTED`, that indicates     concurrent attempts to update the resumable write, caused either by     multiple racing clients or by a single client where the previous     request was timed out on the client side but nonetheless reached the     server. In this case the client should take steps to prevent further     concurrent writes (e.g., increase the timeouts, stop using more than     one process to perform the upload, etc.), and then should follow the     steps below for resuming the upload.   - For resumable errors, the client should call `QueryWriteStatus()` and     then continue writing from the returned `persisted_size`. This may be     less than the amount of data the client previously sent. Note also that     it is acceptable to send data starting at an offset earlier than the     returned `persisted_size`; in this case, the service will skip data at     offsets that were already persisted (without checking that it matches     the previously written data), and write only the data starting from the     persisted offset. This behavior can make client-side handling simpler     in some cases.
+ * 
          The service will not view the object as complete until the client has sent a `WriteObjectRequest` with `finish_write` set to `true`. Sending any requests on a stream after sending a request with `finish_write` set to `true` will cause an error. The client **should** check the response it receives to determine how much data the service was able to commit and whether the service views the object as complete.
+ * 
          Attempting to resume an already finalized object will result in an OK status, with a WriteObjectResponse containing the finalized object's metadata.
